678188 - Scrollbars are invoked when panning is prevented with touch events

Status: RESOLVED WORKSFORME

(Firefox for Android Graveyard :: General, defect)

Description

[Martijn Wargers (dead)]

Attachment: testcase

See testcase, the green block is the area where touch events are used.
Steps to reproduce:
- Make sure that you pan this way that you have no sidebars or url bar visible.
- Now make a swipe in the green area.

Expected result:
- No scroll indicators visible, because no scrolling occurs, because panning is prevented by the touch event handling.

Actual result:
- Scroll indicators appear.

Also weird side-effect.
Make a swipe in the green block -> scroll indicators appear for a while. While the scroll indicators are visible, you aren't able to scroll the page by swiping somewhere outside the green block.

Another weird (maybe even worse) side-effect.
With https://bugzilla.mozilla.org/attachment.cgi?id=560206 and https://bugzilla.mozilla.org/attachment.cgi?id=560207 , testcases from bug 686701:
- Make sure no sidebars or url bar are open.
- Make some wild swipe movements
- Tap on the Android 'back' button.

Now notice, that on the page where you arrive, you aren't able to pan at all.
