Bug 123534

Description:
In an Impress presentation with custom animations of a bulletet list:
1. Expanding a selected animation does not select its children as well.
2. Collapsing an expanded animation deselects all but the last selected animation.


Steps to Reproduce:
1. Create presentation with animated bulleted list with multiple levels of indentation, and one or more additional objects with a custom-animation.
2. Ensure the list collapsed.
3. Select the collapsed parent animation for the list, and an additional animated object.
4. Expand the list.
5. Collapse the list.

Actual Results:
After 4 (expand): only parent element of the list and the additionally animated object are selected (not the child animations)

After 5 (collapse): only the most recently selected animation is selected: all others are deselected.

Expected Results:
After 4 (expand): expect to have all child elements of the animation also selected.

After 5 (collapse): expect to have no change in the selection state (other than not showing any selection for now-hidden child animations for the list).


Reproducible: Always


User Profile Reset: No



Additional Info:
The expected behaviour on expand would be in keeping with the notion that selecting a collapsed head of a list also selects its children. This notion is seen elsewhere with animations when you select a collapsed head of a list and:
- change animation order via drag-and-drop, 
- change animation order via the up/down buttons, or 
- change the start behaviour (like "on click" or "with previous")
