Bug 158917 – [GTK] Layout test fast/scrolling/overflow-scroll-past-max.html is flaky

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: WebKitGTK

[Michael Catanzaro]

Layout test fast/scrolling/overflow-scroll-past-max.html has been failing since it was added in r194486; it's been sometimes passing since r199375. Updating expectations.

I think this is not a failure, it's just that we use a different scroll step on every platform. So, in GTK+ port a scroll wheel step is 40. We normally try to avoid this in tests, by just checking whether the scrollable scrolled or not, no matter how much.

This test is currently crashing, both in WebKitGTK as well as WPE:

I'm closing this bug and reassign the test failure to https://bugs.webkit.org/show_bug.cgi?id=205159
