Tile Pallete always acts as in focus when any dialog box is open and any other non-Editor window is over the Tile Pallete window

How to reproduce:

1. Open the "TilePalette" project
2. Open the "SampleScene"
3. Select the "Grid/Tilemap"
4. Focus on the Scene view
5. Press the "Open Tile Palette" in the Scene view overlay
6. In the Tile Palette window, press "Create new Tile Palette" -> "Create new Tile Palette"
7. Press Create, and then Cancel in the "Create palette into folder"
8. Focus on any other window (outside of the Editor) that overlaps the Tile Palette window
9. Within the new window, press anywhere on it that would overlap with any field in the Tile Palette window
10. Observe the Editor

Expected result: Editor stays behind the focused window
Actual result: Editor gains focus when it is not interacted with
