1004488 - Page has wrong zoom level after pressing BACK button

Status: RESOLVED DUPLICATE of bug 1002426

(Firefox for Android Graveyard :: Toolbar, defect)

Description

[Mark Finkle (:mfinkle) (use needinfo?)]

STR:
1. Start Fennec
2. cnn.com (the desktop version should load)
3. After page fully loads, tap a link to an article
4. Let article fully load. Do not change the zoom level.
5. Press BACK button

Expected: cnn.com page appears at the previous zoom level

Actual: cnn.com loads, but the page is zoomed

I can get this to happen with other desktop style webpages in step #2, not just cnn.com.
It is very reproducible if you always start Fennec fresh. Tapping desktop-style links from the Top Sites page causes this to happen too, but only reliably on a fresh start.

bug 1002426? Is 30 or 31 affected?

This is caused by resolution overriding with the default value, like in bug 1002426.
When we don't scroll or zoom on a page, we don't save the scroll frame session, which leads to this issue when restoring from the default values.
