Comment on attachment 386263 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=386263&action=review The fix looks right to me, TestExpectations need a bit more polish. > LayoutTests/platform/mac-wk2/TestExpectations:-679 > -webkit.org/b/172201 webaudio/silent-audio-interrupted-in-background.html [ Pass Timeout ] This is not the [ Pass Crash ] expectation that Truitt added in https://trac.webkit.org/changeset/253836/webkit
