1132870 - Switching between tabs breaks font inflation

Status: RESOLVED WORKSFORME

(Firefox for Android Graveyard :: General, defect)

Description

[Jan Henning [:JanH]]

Attachment: Example of broken font inflation after switching between tabs

Build: Firefox 35.0.1
Device: Samsung Galaxy S3 Mini (4.1.2)

Steps to reproduce:
1. Load an arbitrary page. For the screenshot, I've used http://www.hq.nasa.gov/alsj/a12/a12.sharp.html
2. Open a new tab and do some browsing there. However make sure that the tab from step 1 doesn't get unloaded from memory/zombified. Actually, at least on my device, it is usually to enough to load http://www.spiegel.de/ (the full page, not the mobile one), wait a minute or so, and then proceed to step 3.
3. Switch back to the original tab from step 1.

Expected Results: 
The page should render normally.

Actual Results:
Quite often, font inflation isn't working properly any more. Line spacing and line breaks are preserved, but the text itself is rendered with a smaller font size - see the attached screenshot.
I've tested it with a fresh profile as well, and I can easily reproduce it there, too.

On the other hand,, at least after playing around for a few minutes, I cannot reproduce this in the current Nightly, so it might be that this problem has been fixed somewhere along the way.

Font inflation will soon be removed from product, bug 1127441.

Attachment: Example of bug in the current FF36 beta

In case anyone is interested, this is how things look when tested with the current FF36 beta. It's an improvement, but it's not completely fixed, either.
As before, the current Nightly still seems to be working fine.

I've finally gotten around to try this in Aurora (37.0a2) as well, and I couldn't reproduce it there either.
