Comment 2

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

Frequent regression from bug 1706867 / bug 1706868?

Comment 3

[Timothy Nikkel (:tnikkel)]

Possible. I'll investigate.

Comment 4

[Timothy Nikkel (:tnikkel)]

Attachment: Bug 1708143. Fix intermittents in test_group_zoomToFocusedInput.html. r?m_kato

There are two kinds of fixes here.

The first is calling waitToClearOutAnyPotentialScrolls after anything that might cause scrolls to make sure all scrolls are done before we move on in the test (so they don't mess us up later). Calling focus on an element is one thing that causes scrolling that may not be obvious.

The second is using promiseTransformEnd to be sure the zoom to focused input animation is done.
