(Xbox game bar didn't capture the cursor)
Steps to reproduce the issue:
1. Put something into a bundle.
2. Move the bundle to the top line of inventory.
3. Move the cursor to the bundle to see what’s inside.
4. Move the cursor up.
Expected result:
When the cursor leaves the bundle, the bundle ui should disapear.
Actual result:
The bundle ui didn’t disappear, and still follows the curcsor.
