All existing checks passes. Failures only in GTK since r255550 according to results.webkit.org link below https://results.webkit.org/?suite=layout-tests&suite=layout-tests&suite=layout-tests&test=imported%2Fw3c%2Fweb-platform-tests%2Fcontent-security-policy%2Fgeneric%2Fgeneric-0_10.sub.html&test=imported%2Fw3c%2Fweb-platform-tests%2Fcss%2Fcss-backgrounds%2Fparsing%2Fbackground-image-computed.sub.html&test=imported%2Fw3c%2Fweb-platform-tests%2Fcss%2Fcss-backgrounds%2Fparsing%2Fborder-image-source-computed.sub.html
Three more tests that are timing out after r255550: * fast/forms/image/image-error-event-modifies-type-crash.html [ Slow ] * http/tests/contentextensions/make-https.html [ Slow ] * js/dom/custom-constructors.html [ Slow ]
* imported/w3c/web-platform-tests/content-security-policy/generic/generic-0_10.sub.html * imported/w3c/web-platform-tests/css/css-backgrounds/parsing/background-image-computed.sub.html * imported/w3c/web-platform-tests/css/css-backgrounds/parsing/border-image-source-computed.sub.html were fixed in r256423.
I'm closing this bug since the main issues pointed by this bug were already fixed in r256423. As for the remaining failures pointing to this bug: webkit.org/b/207246 fast/forms/image/image-error-event-modifies-type-crash.html [ Slow ] webkit.org/b/207246 http/tests/contentextensions/make-https.html [ Slow ] webkit.org/b/207246 js/dom/custom-constructors.html [ Slow ] they seem unrelated and the tests are didn't report an error since r258104, so I'm removing them from test expectations.
