The two attached testcases render differently, even though the only difference between the two is the presence or absence of a 'document.body.offsetTop;' This probably means there's some bug in the incremental style recalculation logic. The patch at https://bugs.webkit.org/show_bug.cgi?id=46761 exposes this on a few layout tests, but this bug exists with or without that patch.

Created attachment 123403 [details] testcase without the document.body.offsetTop This version makes it slightly easier to see where various bits of text are coming from

The tests marking as failing here are suddenly randomly passing, or failing in different ways... I'm simply updating the test_expectations file for now.
