Attached video titebar bug.mp4

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/118.0

Steps to reproduce:

Click and hold on titlebar, drag downwards

Actual results:

browser exits from maximized, as expected, but close button is highlighted on its own for no reason.

Expected results:

The close button should remain idle since it has not been interacted with. It doesn't highlight when dragging in unmaximized mode, only when transitioning from maximized to unmaximized.

I can reproduce this issue on Nightly120.0a1 Windows10.
And I can also reproduce on Firefox69.0....

STR:
0. Enable Snap windows from Windows settings.

  1. Open Firefox.
  2. Switch to normal window size mode.
  3. Drag the title bar to the top edge of the screen with the mouse. Do not release the mouse button yet.
  4. Remember the position of the close button.
  5. Release the mouse button to maximize the browser.
  6. Press the mouse button at the position memorized in step 4. Then drag downward.

NOTE:
If the position to be memorized in step 4 is another button (e.g. List All Tabs button), that button will be highlighted (mouse hover status) in step 6.
