/WPE/TestWebExtensions
        /webkit/WebKitWebView/web-process-crashed

Output:

  /webkit/WebKitWebView/web-process-crashed:                          FAIL
WPE-FDO-FATAL-WARNING: Instance::dispatchFrameCallbacks(): Cannot find surface with bridgeId 1 in view backend map. Probably the associated surface is gone due to a premature exit in the client side

(/app/webkit/Tools/glib/../../WebKitBuild/Release/bin/TestWebKitAPI/WPE/TestWebExtensions:778): WPE-FDO-WARNING **: 06:40:11.689: Instance::dispatchFrameCallbacks(): Cannot find surface with bridgeId 1 in view backend map. Probably the associated surface is gone due to a premature exit in the client side



In the release bot, the first failure was in the build #2602 for identifier 240345@main. Since this revision, it failed 31 out of 41 runs.

Locally:

Laptop: 4 fails in 20 runs
Desktop: 7 fails in 20 runs

In a manual build outside Flatpak, no errors in 10 runs.

I guess that's expected to happen in case of web process crash, so maybe we can just make warnings non fatal at that point or not use g_warning in wpe-fdo

Indeed. With this patch, it's consistently passing.

Ok, I think we should still check if we can remove the g_warning in wpe-fdo, because thi might hide other warnings happening.
