Studio UI Editor not deselecting properly

If you select a Gui object in the explorer and deselect it from by clicking in the viewport, the UI editor will be stuck on the screen. The next time you select a Gui object from the explorer, when you move your mouse to the viewport, the Gui object will be stuck as dragging.

This only happens in this one place. hs2 - Roblox.
My place has team create enabled. I have tried copying all my Gui to another blank place and this bug does NOT occur. I have tried disabling all my plugins and this bug still occurs.

I noticed this started to happen May 31, 2021.

Notice I am not selecting anything in the explorer and the UI editor lines are stuck on the screen.

When I select the object in the explorer, and move over to the viewport, the frame is stuck as dragging.

Here is another post describing the issue: Roblox Studio UI Editing not working properly

Reproduction Steps:

  1. Insert a ScreenGui into StarterGui
  2. Insert a Frame or any GuiObject into the ScreenGui
  3. Select the Frame from the explorer.
  4. Deselect the Frame by clicking in the viewport.
  5. Select the Frame again from the explorer.
  6. Now when you move your mouse into the viewport, the Frame should be stuck as dragging.
