Steps to reproduce:
1. Open any Project with the new Input System Package Installed
2. Navigate to Edit > Project Settings > Input System Package
3. In the Actions section create a New Action
4. Expand the newly created Action and select the "<No Binding>" and delete it
5. For that same Action create a New Binding
6. While it's auto selected after creation click on the Binding Path dropdown menu in the Binding Properties panel
Actual results: The Binding is deselected while the dropdown menu is still open and the Binding Properties panel doesn't reflect the binding
Expected results: Binding is not deselected and the Binding Properties menu reflects the correct Binding
Reproducible with versions: 1.8.0, 1.14.2
Tested on (OS): Windows 11
Note: Issue does not reproduce when opening the Actions Asset as a separate Window
