Multiple warnings are thrown after editing Package Manifest via Inspector while Package Manager window is hidden

Steps to reproduce:

1. Move Package Manager window and the Inspector window in the same panel (so focusing on one hides the other)
2. From Package Manager window, select a Custom package
3. Click Manage -> Edit Manifest
4. In the Inspector window, make some changes
5. Apply the changes

Actual results: Multiple "Trying to access the DPI setting of a visual element that is not on a panel." warnings are thrown
