Description Shawn Roberts 2019-04-29 12:44:57 PDT
The following layout test is flaky on iOS Simulator Debug

fast/events/autoscroll-when-input-is-offscreen.html

Probable cause:

Test was added in https://trac.webkit.org/changeset/244141/webkit and had some flaky behavior on Release iOS Sim Release

After fix in https://trac.webkit.org/changeset/244210/webkit the test is failing quite consistently on iOS Sim Debug. 

Reproduced with:

run-webkit-tests fast/events/autoscroll-when-input-is-offscreen.html --iterations 50 -f --ios-simulator --debug

 This test focuses a form, them scrolls to the bottom of the page. Then text is entered in the form, and we check to make sure the page has scrolled so that the input is visible again.
-PASS: page has scrolled back to the top to show the element that has text being entered into it.
+FAIL: page has failed to scroll when entering text into a form that is offscreen.
