1497762 - Fixed-position footer on KQED snaps upwards from bottom of viewport when you scroll to bottom of page

Status: VERIFIED DUPLICATE of bug 1495055

(Core :: Panning and Zooming, defect, P3)

Description

[Daniel Holbert [:dholbert]]

STR:
 1. Visit https://www.kqed.org/radio/program/live-from-here-highlights in Firefox Nightly for Android.

 2. Wait for the page to finish loading, as reported by the throbber bar. (might take a few seconds for ads/etc to finish loading)

 3. Scroll to the bottom of the page.

ACTUAL RESULTS:
The "Play|Trending|Search" footer bar snaps upwards a few pixels (leaving awkward dead space at the bottom).

EXPECTED RESULTS:
That footer bar should remain snapped to the bottom of the viewport. It's styled as "position:fixed; top:auto; bottom:0", so it should stay at the bottom.


mozregression gives me this regression range:
https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=2d1d32212c1e4107bef4d24dbbe2f12adca11837&tochange=77433149bfdcc82287acaed94b942818785b556e

In that range, it looks like bug 1465616 is the likely culprit.  (Looking at that bug, it's possible this is a dupe of bug 1495055, but we'll see when its patch re-lands I guess... for now, tentatively marking bug 1495055 as a dependency, since it seems likely it'll help here.)

This is fixed by the updated patch in bug 1495055; marking as a dupe.

That's great to hear! Thanks.  (I'll remove that bug from the dependency field, too, then.)

Just verified that I can't reproduce this in Nightly on Android anymore (which makes sense, since the dupe-target bug's patch has landed).

--> Marking as a verified dupe.
