Description Shawn Roberts 2019-03-12 12:19:34 PDT
The following layout test is failing on Mac WK2 and Mac WK2 Debug

scrollingcoordinator/mac/multiple-fixed.html

Probable cause:

Test is failing as of https://trac.webkit.org/changeset/242313/webkit . Ran tests locally with newest revision 242800, and r242313 and got same timeout, image diff.
Test is failing locally with debug revision 242805 as well.

Reproduced with :

run-webkit-tests scrollingcoordinator/mac/multiple-fixed.html --iterations 500 -f --no-retry
run-webkit-tests scrollingcoordinator/mac/multiple-fixed.html -f --iterations 500 --no-retry --debug

Image makes it look like we're catching it in a rubber-band.

marked test as timeout in https://trac.webkit.org/changeset/246806/webkit while waiting on fix
