BHV-16740: Block focus and tap event when listActions is open

Issue:
- Panel body items can be focused in pointer mode when listActions are open
- Focus can not move from listActions to panel body but can move opposite direction.

Fix:
- We can block tap and focus event while listActions are open without adding scrim.
