1509563 - The toolbar isn't hidden when scrolling down the page on some sites

Status: RESOLVED INCOMPLETE

(Firefox for Android Graveyard :: Toolbar, defect, P3)

Description

[csheany]

User Agent: Mozilla/5.0 (Android 7.1.1; Tablet; rv:65.0) Gecko/65.0 Firefox/65.0

Steps to reproduce:

1. Open https://bugzilla.mozilla.org
2. View the bug of your choosing
2. Scroll the page


Actual results:

The toolbar remains visible. Zooming in and then scrolling produces the correct behavior.


Expected results:

The toolbar should be hidden.

The behaviour here is due to the fact that the scrollable element on Bugzilla isn't the page itself, but a scrollable <div> (which takes up all the space on the page except the header bar).

Movement of the browser toolbar is only hooked up to scrolling of the page itself.

I doubt we're going to implement dynamic toolbar movement for subframe scrolling, but I'll let Randall make that call.

Also filed this against Bugzilla itself (bug 1435417), but never got any response.

Thanks for the report!
I will mark this bug as a duplicate of 1435417 since is the same issue.

Not really. They're old bugs and documentation concerning our initial implementation of asynchronous scrolling infrastructure on Android.

Thank you.

I know it's a long shot but I figured it couldn't hurt :)

Should the summary be edited?

Comment 8

[Botond Ballo [:botond]]

I've edited the summary to reflect that this only happens on some sites. People can read comment 1 for details on which kind of sites it affects.
