Does this reproduce on 1.1?

Comment 2

The issue doesn't reproduce on 1.1 or 1.3, the bug is written for 1.2 MozRIL
User is unable to select an app they cannot see.

That doesn't make a whole lot of sense. The affected flag here states this reproduces on 1.3. Please double check this with gbennett.

The YouTube video shows how easy and fast it reproduces on 1.2, you can retrieve any app even when gently touching near to an app.
But on 1.3 it's took about 10-20 seconds of fast touching close to the edge of the first screen to retrieve the closest app from the second screen

Sorry about the confusion in comment zero. I checked 1.3, 1.2, and 1.1 and all 3 repro but 1.3 and 1.1 are pretty difficult. 1.1 required quite the finesse at an acute angle for about 15 seconds. Updated tracking flags.

The video attachment shows a different way how to repro this issue on 1.2 but I cannot reproduce the same on 1.1 and 1.3
