Permanent ui-test-arm failure of fileDownloadTest

[Archaeopteryx]

Log: https://treeherder.mozilla.org/logviewer?job_id=398214814&repo=reference-browser
This test fails permanently (times out: test runs too long and gets terminated).

First failure is for a9445a0, last successful run is befd344

Was bug 1800611 (cc @JohanLorenzo ) the only change between those A-C versions? This should not cause test issues - is this the only test which tries to save a file in any way?

@AndiAJ Please take a look next week.

Thanks for the ping! I wouldn't be surprised if the new version scheme breaks some assumptions. I can't access the Firebase logs on reference-browser. Would it be possible to get access to them?

The test is getting stuck for 30 minutes in the notification shade. Tried using the Fenix approach to scrolling the shade in #2135 but still timed out. Not sure why Fenix is working, but disabling for investigation so commits don't timeout.

The issue is scrolling the notification from the tray into view
