Layout tests fast/backgrounds/background-leakage-transforms.html and fast/text/emphasis-overlap.html are failing. The regression(s) occurred somewhere between r227901-227957, inclusive. That's a pretty big range of commits; I guess our test bot was having a bad day. Very bad. Image diffs: https://build.webkit.org/results/GTK%20Linux%2064-bit%20Release%20(Tests)/r228441%20(5465)/retries/fast/backgrounds/background-leakage-transforms-diffs.html https://build.webkit.org/results/GTK%20Linux%2064-bit%20Release%20(Tests)/r228441%20(5465)/retries/fast/text/emphasis-overlap-diffs.html Updating expectations accordingly.
It is already fixed because the expectations was updated in r254184 (https://trac.webkit.org/changeset/252598/webkit#file82) The https://webkit.org/b/206079 removes the expectation in GTK+ from platform/gtk/TestExpectations for related to this defect.
