(Core :: Disability Access APIs, defect, P1)

Description

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

+++ This bug was initially created as a clone of Bug #1760880 +++

Assuming this is GeckoView related as there is nothing else on A-C upgrade that is causing issues.

So therefore last working geckoview version: 102.0.20220513093538
Broken geckoview version: 102.0.20220514065807

UiAutomator which we use for locating elements in Gecko on Android is not working, thus all interactions with web content (e.g, clicking a link) are not working.
