Steps to reproduce:

  1. Opend a JIRA bug report with firefox for Andoird
  2. scrolled to bottom and zommed a bit

Actual results:

the content seems to be cut-off, there is a dead area on the bottom of the page where no content is shown and scroll-input is ignored: https://youtu.be/noH_-IATW7Y

Expected results:

the page should behave the same as with google chrome for android.
the full content should be shown, zooming and scrolling should work as expected.

Hi Diana, can you check if this also happens in Fenix?

Hi, yes of course, I managed to reproduce the issue with Google Pixel 3a (Android 9) and Sony Xperia Z5 (Android 7.0.0) on Firefox Release 68.5.0 and Firefox Beta 68.6b2.
On Firefox Preview Nightly 200219 (Build #20500606) GV: 75.0a1-20200218093736 the issue does not reproduce, fortunately.
Please view video.

I will mark the ticket as NEW for fennec.

Comment 3 sounds like it happens on Fennec but not Fenix. So this should be WONTFIX?

Possibly related to bug 1478690, since it looks like the displayport for the subframe is not placed correctly after zooming in on the root frame.

We sometimes fix Fennec bugs, or uplift existing fixes to ESR, though admittedly that's been happening less often as time has gone on.

Based on the symptoms, I'd say this is likely the same issue as bug 1546222, which is a dupe of bug 1565512, which was wontfixed for 68esr.

This theory seems to be wrong.

Mozregression in fact points to bug 1514429, which wasn't considered for ESR uplift (and probably shouldn't be given its regression risk).
