How to reproduce:
1. Open the attached project
2. Open the two VFX Assets in Project Browser (They should open 2 different windows)
3. Try selecting the two Assets and observe that the Inspector updates
4. Select a Node in one of the Assets and click on the Blackboard where there are no other Nodes and observe that the Inspector changes to VFX Asset Settings
5. Open the other Asset by switching windows and not opening the Asset itself and click anywhere on the Blackboard without selecting a Node first and observe the Inspector

Actual result: Clicking anywhere on the Blackboard if no Node was previously selected does not show the VFX Asset Settings, but does show it if a Node was previously selected
Expected result: Clicking anywhere on the Blackboard dead space could show the VFX Asset Settings, like it does when a Node is selected and then unfocused when clicking in the Blackboard

Reproducible with: 2022.3.12f1, 2023.1.19f1, 2023.2.0a15, 2023.3.0a11
Not reproducible: 2021.3.31f1 (VFX Assets open only in one window)
