[Bug]: Edge channel browser process crashes/closes page context during cross-origin SAML/OIDC redirect in v1.62.0

[David-Genrich]

Version

1.62.0

Steps to reproduce

1. Configure Playwright 1.62.0 in Java using the Microsoft Edge channel:

BrowserType.LaunchOptions launchOptions = new BrowserType.LaunchOptions()
        .setHeadless(false)
        .setChannel("msedge");

2. Navigate to an enterprise application URL protected by an OIDC / SAML 2.0 gateway (IBM Security Access Manager integrated with Microsoft Entra ID / Azure AD).

3. Fill in user credentials and submit the form.

4. On the Entra ID "Keep Me Signed In" (KMSI) screen (login.microsoftonline.com/kmsi), click the final submit button (#idSIButton9).

5. Observe the browser context behavior as Entra ID executes the top-level POST redirect back to the application's OIDC authorization endpoint (/oidc/endpoint/default/authorize).

Expected behavior

The Edge browser tab should process the top-level OIDC authorization redirect cleanly, remain open, and navigate to the target application URL.

Actual behavior

During the SAML/OIDC POST redirect handoff immediately following the KMSI submission, the active browser page target closes unexpectedly (PageImpl.didClose event fires). Any subsequent Playwright navigation waiter or frame listener fails immediately with:
com.microsoft.playwright.PlaywrightException: Target page, context or browser has been closed

Note: This failure is isolated strictly to the Edge channel binary on 1.62.0. Running the exact same test flow on 1.62.0 using bundled Chromium, Google Chrome (chrome), or Firefox (firefox) works as expected without closing the page target.

Additional context

• Regression Window: Works cleanly in Playwright 1.59.0 (all channels). Fails in 1.62.0 when using setChannel("msedge").

• Telemetry Observation: Console logs show Microsoft BSSO telemetry attempting native broker calls prior to the crash: BSSO Telemetry: {"result":"Error","error":"bssoNotSupported"... "window.navigator.msLaunchUri is not available"}.
