1121849 - (App-grouping) After collapse the group, it results in group moving if the 1st group's top position is not at the top of the screen

Status: VERIFIED INVALID

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

Description

[Hermes Cheng (inactive after July 27, 2015)]

*Spec:
In page 7 of 2.2 UX spec [1], it defines that when a group is collapsed, its top position stays fixed and the collapsing group does not move.

*Current behavior:
After I collapse a group, the screen is scrolled down to reach the bottom of the screen automatically if the last group's bottom position is not there. See video [2], [3].

Correct the behavior: 
After collapsing a group, the screen is automatically scrolled down to let the top position of 1st group reach the top of screen if the 1st group is not there.

I don't really understand what's being described here, but in both videos, after you've collapsed the group, the grid is no longer scrollable - unless we artificially pad out the grid so that it allows you to scroll to the extent that would exist if all groups were expanded, this will always be a bug (and that would most certainly be an inferior experience).

Marking this as invalid - If I've misunderstood, please reopen.
