COOP Breaks Popup Opener

coop-popup-opener-null

COOP policy forces cross-origin popups into a 'new with no opener' context, so window.open returns null and opener/messaging assumptions fail; downstream iframe messaging and printer/Stripe flows deadlock or lose access to the parent.

I am unable to change the statte of the `open`-hook inside the object — I am using Radix-UI and I want to create a service for creating toasts. Tension: After 5 seconds (default value) `onOpenChange`is called to set open=false through a hook. This does not work. Outcome: This does not work.

Dialog box flickers when opening and closing

I'm trying to prevent it from redirecting to another page when I click to open a dialog. Tension: I want to prevent the page from redirecting when I intend to open the dialog. Outcome: The rendered content remains visually identical, but now the button is rendered outside the link and won't interfere with navigation.

making it impossible to interact with the dropdown items from tagify. Tension: hadcn is completely disabling interaction with elements outside the dialog and its content.

requests with the forbidden fields sailed through to the write path. Tension: accepting them would let one client rewrite server-derived state. Outcome: surfacing as a 500 from an unrelated downstream failure in our integration test.

AADSTS9002325: Proof Key for Code Exchange is required for cross-origin authorization code redemption. Tension: redirects uris not matching.

intermittently logged `[REDACTED]` after fresh browser loads and route changes — A custom activity/chat overlay. Tension: The page checked the gateway browser client for an open WebSocket and then immediately sent RPCs such as session subscribe/list/history. Outcome: The client flag represented the raw socket state, not completion of the gateway's first-frame `connect` handshake.

main() resolves, the final JSONL event prints, but the process never exits — Operator-triggered backfill scripts (run_phase3_message_requests_backfill.ts, run_phase3_messages_backfill.ts). Tension: CI/operator scripts kill it with SIGINT or timeout.

Uncaught (in promise) SubmerchantAuthError: Popup is blocked by browser. — once i click it. Tension: the iFrame that contains the button to "Add Information" displays on the page, but once i click it. Outcome: Even so, a popup does open but shows just a loading indicator.

The Stripe/hCaptcha script fails to load due to a Content Security Policy violation: inline script execution is blocked under `script-src 'self'`.

if the customer changes their mind and clicks the [X] icon to close the modal — if the Affirm or Klarna payment options are used, it shows a payment modal for the customer to complete the process. Tension: This will cause the purchase payment to not go thru but will still send all the payment details to the `return_url` as if they did. Outcome: It's normal.

the redirect would be blocked by browser after successful payment — if I load the addin in a office web (microsoft 365) excel document in the browser. Tension: it is actually trying to navigate the top level window. Outcome: How can i achieve the behavior that the taskpane addin that is hosted inside should only be redirected?

chat room content flashes briefly before closing after navigation

Embedding a CPQ web app as an iframe inside Salesforce fails to persist authentication cookies/session for API calls. Login in a new tab isn’t recognized inside the Salesforce iframe, preventing authorized requests.

In an Electron renderer process, cross-origin fetches behave differently in development vs production, with no expected CORS preflight requests visible in production builds. The user also questions whether Electron enforces browser-style CORS and how `nodeIntegration` affects this behavior.

Is possible to call cl:open by another way? — I need to hide dungerous function(s), for example, cl:open for thirdparty code downloaded from internet. Outcome: There will be more.

callback request is not secure enough for production

Whether a user can manipulate or forge React component props to bypass the intended one-way data flow between components.

" would like to access data from other apps" — On Sonoma (macOS 14) i keep getting the dialog. Tension: It does NOT try to access anothers app AppContainer. Outcome: I am quite lost, just seeing that others got this issue too.

When a page is served with Cross-Origin-Opener-Policy: same-origin inside a cross-origin iframe, calling window.open returns null in the parent page console, even though the popup tab opens successfully.

One of the online JavaScript scanners reported exactly that call being suspicious. Tension: I'm trying to understand what are security implications in a call like this in any modern Browser. Outcome: it will still work.

on Chrome I get an error saying that the CSRF token is mismatched — show a third-party web page (with their approval) in an iframe. Tension: This site has a different domain to my parent site. Outcome: The site displays fine on firefox.

I'm unable to interact with the original tab — when switches back to the original tab without closing the print dialog. Tension: Not even right click is working. Outcome: both tabs are blocked.

s a UI library’s dialog component. Tension: If I do that however, then the `onOpen` callback also gets called whenever the `onOpen` callback changes, which is not the behaviour that I want. Outcome: I want it only to be called when the `open` prop changes from `false` to `true`.

The postMessage communication between two iframes works on desktop browsers but fails to load/pass data on iOS and Android browsers. As a result, the iframe content never receives the message.

TypeError: Cannot read properties of undefined (reading 'ReactCurrentOwner'). Outcome: Has anybody seen this before?

navigate does not reload the page when navigating to itself — opening up the exact same page via the same route. Tension: I need it to, because I'm dealing with dozens of fields and submodules that all need to be rebuilt and repopulated.

The Paddle.com overlay checkout fails when opened from a locally hosted Django site, showing a generic "something went wrong" dialog.

nothing is displayed on the pop-up window — When I click on the "sign up with google button".

Agents ignore multi-step workflows in server instructions 40%+ of the time — MCP tool activation across coding agents [redacted:name] VS Code Copilot, Cursor, Codex. Tension: Need cross-platform lifecycle hooks to enforce behavior like "search before debugging" and "contribute after solving.". Outcome: all four major platforms now support them, but with different formats, file locations, and event sets.
