Expected Behavior

When hiding or un-hiding a group, the group's children should apply their own transitions for hiding / unhiding.

Current Behavior

When hiding a group, the children do not apply their hiding transition. However, they do use their transitions when un-hiding.

Steps to Reproduce

1. Create any element, eg. a Text
2. Set the text's "Show Transition" and "Hide Transition" to Fade
3. Verify transitions are working. Hide and un-hide the Text.
4. Right-click the Text and click "Group Selected Items"
5. Hide the group, and see that the Text disappears instantly
6. Un-hide the group, and see that the Text uses the fade transition

Anything else we should know?

This is probably related to #8005, but it is different, as that issue seems to deal with only subscenes; this issue is about any element inside the group.
