svg/custom/object-sizing-explicit-width.xhtml

This test began failing on Mac wk2 recently with the changes in r257840
This test is already known to be flaky on Mac debug wk1 from https://bugs.webkit.org/show_bug.cgi?id=181058
the diff is very different from that bug though

Comment 2 Truitt Savell 2020-03-13 14:32:24 PDT

I am able to reproduce this issue with command:
run-webkit-tests --iterations 2000 --exit-after-n-failures 1 --exit-after-n-crashes-or-timeouts 1 --debug-rwt-logging --no-retry --force --no-build -f svg/custom/object-sizing-explicit-width.xhtml

This reproduces on r257840 but not 257839

Comment 3 Truitt Savell 2020-03-13 14:39:49 PDT

Mark test as failing while it is investigated https://trac.webkit.org/changeset/258432/webkit
