1133383 - [Homescreen] Under certain circumstances in edit mode, the homescreen will scroll while the user is moving an icon

Status: VERIFIED DUPLICATE of bug 1118006

(Firefox OS Graveyard :: Gaia::Homescreen, defect)

Description

[Théo Chevalier]

Attachment: Video of the issue

STR:
Enter in Edit mode
2. Long press an icon and move it elsewhere.
3. Quickly start long tapping on another icon (you have to start long tapping before the first icon has finished moving to its new spot)

Actual result:
As you can see on the attached video , if you move the icon on the screen, the homescreen is scrolling at the same time, so the icon actually stays at the same spot (you can only move it horizontally).

Expected result:
The homescreen doesn't scroll and behave as usual

Might be a dupe, but since it's pretty difficult to describe, couldn't find any related bugs.

Tested on Flame with current master + v18D

This is possibly an APZ issue, or something that we are doing to trigger some weirdness in the platform. Need to dig into this a bit further.

Adding qawanted to see if we can get a branch check, and occurrence rate.

I can repro this bug on Flame v2.2,but can't repro this bug on Flame v2.0&2.1&3.0.

See attachments: verify_v2.2.MP4 and logcat_0525.txt
Reproduce rate: 5/10

Repro STR:
1.Long tap a icon and drag it up or down on Homescreen.
2.Quickly start long tap another icon as soon as the first icon has finished moving to its new spot.
3.Then try to move the icon.
**The homescreen is scrolling at the same time, so the icon actually stays at the same spot.  --KO
**After several move,you can move it to elsewhere.

A note, my patch in bug 1118006 fixes this - I'll try to get that bug done this week, but if not I'll handle this separately.
