Bug in Tweaks caused by switching window buttons to left

Switching window buttons to left caused flickering of the Tweaks menu and inability to (sanely) navigate through it. (I can search for a term, and click on different menu options after clicking the “back” arrow in title bar.)

However, switching the placement back to right doesn’t work. Other switches seems to work.

P. S.: Is there another way to place the buttons back to right? I’ve looked through dconf but found nothing.
