The following test is consistently failing with text diff in macOS wk1 and also flaky in EWS.
The test started failing with more frequency after 291478@main. 

fullscreen/full-screen-document-background-color.html is a 

 RUN(frame.src = "resources/backdrop-red-on-green.html")
 EVENT(load)
 RUN(enterFullscreen())
-EXPECTED (internals.documentBackgroundColor() == 'rgb(0, 128, 0)') OK
+EXPECTED (internals.documentBackgroundColor() == 'rgb(0, 128, 0)'), OBSERVED 'rgb(255, 0, 0)' FAIL
 RUN(exitFullscreen())
 EXPECTED (internals.documentBackgroundColor() == 'rgb(255, 255, 255)') OK
 END OF TEST
