favicon-loads-with-images-disabled.html has LoadsImagesAutomatically=false. It makes some subsequent tests fail. Unexpected flakiness: text-only failures (2) http/tests/misc/image-blocked-src-change.html [ Pass Failure ] Unexpected flakiness: timeouts (2) http/tests/misc/image-checks-for-accept.html [ Timeout Pass ]

This isn't producible with Mac port. How does it reset the pref? > run-webkit-tests http/tests/misc/favicon-loads-with-icon-loading-override.html http/tests/misc/image-blocked-src-change.html --iterations=2 --child-processes=1

The implementations of TestController::platformPreferences and TestController::platformAdjustContext are different. TestController::ensureViewSupportsOptionsForTest decides to create a new webview because test options don't match. However, non-Cocoa TestController::platformPreferences constantly returns a same preference object. Cocoa's TestController::platformAdjustContext re-initializes it.

The result of "grep -r LoadsImagesAutomatically *" in LayoutTests directory: > fast/loader/display-image-unset-can-block-image-and-can-reload-in-place.html\012: internals.settings.setLoadsImagesAutomatically(false); > fast/loader/display-image-unset-can-block-image-and-can-reload-in-place.html\024: internals.settings.setLoadsImagesAutomatically(true); > http/tests/cache/display-image-unset-allows-cached-image-load.html\021: window.internals.settings.setLoadsImagesAutomatically(false); > http/tests/misc/favicon-loads-with-icon-loading-override.html\01:<html><!-- webkit-test-runner [ LoadsImagesAutomatically=false ] --> > http/tests/misc/favicon-loads-with-images-disabled.html\01:<html><!-- webkit-test-runner [ LoadsImagesAutomatically=false LoadsSiteIconsIgnoringImageLoadingPreference=false ] --> > svg/as-image/svg-image-with-data-uri-images-disabled.html\014: internals.settings.setLoadsImagesAutomatically(false); LoadsImagesAutomatically=false webkit-test-runner header is used only by two tests. wk2/TestExpectations skipps both. > webkit.org/b/115809 http/tests/misc/favicon-loads-with-images-disabled.html > webkit.org/b/115809 http/tests/misc/favicon-loads-with-icon-loading-override.html This is the reason GTK and WPE layout tests don't observe this bug. wincairo/TestExpectations marks it as Failure for WinCairo WK1. > http/tests/misc/favicon-loads-with-icon-loading-override.html [ Failure ] This is the reason only WinCairo detects.

Comment on attachment 465113 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=465113&action=review > Tools/WebKitTestRunner/TestController.cpp:3082 > + WKPageGroupSetPreferences(m_pageGroup.get(), WKPreferencesCreate()); This pref leaks. I have to adopt it.
