Overlays are immediately undocked when the Overlay is docked to the right side of Scene View and the Overlay's Handle is clicked

Steps to reproduce:

1. Open any Project and open Scene View
2. Dock any Overlay in the bottom or top right corner
3. Dock any other Overlay either on top of it if you placed the first Overlay at the bottom or below it if you placed the first Overlay at the top
4. Click once on the first Overlays Handle (=)

Actual results: The first Overlay is immediately undocked and the second Overlay takes the first ones place in the corner dock. When docking an Overlay in the right side corners and then clicking the Handle, the docking indicator changes indicating that the Overlay is undocked

Expected results: The Overlay is not immediately undocked when the handle is clicked
