I don't see how it could. My patch only touched adb, which should only affect android platforms.

The test run from comment 0 has this screenshot linked as one of the artifacts at the top:
https://queue.taskcluster.net/v1/task/b0IyqpI9QYWca6efLcXeoQ/runs/0/artifacts/public/test_info/mozilla-test-fail-screenshot_xithhf.png

That seems to show that Windows has popped up a modal dialog ("Important updates are pending"), probably stealing focus and breaking the test as a result.

Here's another log with the same failure, and its screenshot which shows the same dialog:

https://queue.taskcluster.net/v1/task/ZothYEujTy--L_TA3c0KUA/runs/0/artifacts/public/test_info/mozilla-test-fail-screenshot_wczw1y.png

So I think that windows dialog is at fault.  This probably started happening just recently because:
 (a) Microsoft just recently published some important windows updates
 (b) ...or: maybe this has always been happening, but it's less problematic if it pops up during a test that cares less about having focus.
(didn't finish my thought for (b) -- was gonna say "...and perhaps some recent test rebucketing bumped this test to be visited at just the right time during our test-run-lifetime that it's possible it intersects with this dialog".)

(no idea if this is actually the case; just throwing out possible explanations.)

This is still happening.
