+++ This bug was initially created as a clone of Bug #1769510 +++
Previous cases of this issue: affected a lot more tests, but after the latest fix, it still left a few tests broken.
Assuming this is GeckoView related as there is nothing else on A-C upgrade that is causing issues.
Started with AC versions: 102.0.20220524015637 and 102.0.20220524143152

UiAutomator, which we use for locating elements in Gecko on Android, is not working for validating page content in some UI tests, on the test pages from this domain:
the "Address not found" page of a bad URL

Failing tests reports logged:
from Focus:

from Fenix:

I think I fixed this issue in bug 1772019. Can you track it when it lands in a-c and see if it does the trick?

Fixed the Fenix errors for me locally, but I coudn't figure out how to load a local geckoview into Focus to test.

Hi! We re-ran the affected tests and we can confirm that the latest fix is working.
For this: I couldn't yet find a proof that it's related to the same issue, so I'll close this as fixed. Thank you!

Resolution: --- → FIXED

Note that eeejay's fix landed in 103. But we're preffing the feature off for 102 in bug 1772165, so it shouldn't be affected there eventually.
