Steps to reproduce
Click twice quickly on the left arrow in the titlebar of the window – the one that looks like this:

Expected result
Clicking two (or more) times in quick succession on the left arrow should simply page back through the history of pages you’ve visited, and not maximise the window – the window should only maximise if you double click on the title bar outside of the arrows.
Actual result
The window is maximised. If the window is already maximised, then the window size is restored.
Environment
Mac OS 10.15.7
Obsidian version 0.12.13
Additional information
The same thing happens when clicking twice quickly on the right arrow as well.
