Bug 181831 – [High Sierra] Layout Test fast/forms/searchfield-heights.html is a flaky failure

• Component: New Bugs
• Status: NEW

[Ryan Haddad]

The following layout test is flaky on High Sierra

fast/forms/searchfield-heights.html

Probable cause:

Unknown, this test has been flaky on the leaks bot for a while, but as of 3 days ago it has become very flaky across all High Sierra queues.

Thanks! It is probably still worth trying to find out what caused this to become so frequent.

Agreed. I will try to find a regression point on this one.

I have been unable to find a regression point so far, but this has started to become flaky on WK1 as well. Adjusted expectations:
