I would add that the arrangement of window controls does not revert to the expected layout when switching from Light back to Human or other themes, nor is there any way for a user to choose how they want their windows laid out except for the above workaround. It's great that it's an aesthetic decision, but a) it should only impact the new themes, and b) should be more readily user-controlled in the event that it is unwelcome.
