The new test scrollingcoordinator/ios/ui-scroll-fixed.html

added in https://trac.webkit.org/changeset/242683/webkit

is a flakey image failure on iOS release wk2.

History:

looks like a scrollbar is inadvertently visible when the results are taken.
Comment 7 Simon Fraser (smfr) 2019-03-15 11:11:39 PDT
Yes, I need to either add code to hide scrollbars, or make the timeout longer.
