Deferred SignalBehavior breaks UI editor dragging

Setting Workspace.SignalBehavior to Deferred causes the UI editor’s dragging feature to become “sticky”.
This first happened to me a couple weeks ago (don’t know when exactly) but can be reproduced 100% of the time.

Reproduction Steps

  1. Set Workspace.SignalBehavior to Deferred.
  2. Select any GuiObject.
  3. Click the viewport to deselect the gui.
    :x:The resize handles will remain on screen.
  4. Select another gui.
    :x:The last selected gui will “stick” to your cursor.

Can confirm this is still an issue. (Might be fixed tomorrow by chance, I’ll edit this if it does.)
