Marked test expectations https://trac.webkit.org/changeset/283725/webkit

Regression range: https://trac.webkit.org/log/webkit/?action=stop_on_copy&mode=stop_on_copy&rev=282160&stop_rev=282149&limit=100

Comment 4 Ryan Haddad 2021-10-15 16:02:48 PDT

The test is using getBoundingClientRect(), so this must be related to https://trac.webkit.org/changeset/282150/webkit somehow.
