The failing tests are fast/css/word-spacing-characters.html and fast/css/word-spacing-characters-complex-text.html
The tests were added by the patch for https://bugs.webkit.org/show_bug.cgi?id=89826 in r125578. The first build
which has layout test results after that is 125583, hence it is not clear if the tests passed when checked in or not.
Looking into platform/mac/TestExpectations showed that these tests were already added as expected failures. But the "MAC" configuration modifier in the test expectations line is causing them to be ignored.
// Added by bug 89826
BUGWK94008 MAC : fast/css/word-spacing-characters.html = IMAGE
BUGWK94003 MAC : fast/css/word-spacing-characters-complex-text.html = IMAGE
Removing the "MAC" modifier, causes the lines to take effect and the tests are skipped.
