Overlapping windows

[MatteoDelOmbra]

Describe the bug
When you have opened two windows vertically, and the one on the left has fixed min width rescaling windows create a bug. You can resize right window more than it should be possible considering min width of the second window. This creates scenario, where Right window "overlapping" left window. When focus is on the right it's not a problem, but when focus is on the left window, you can click on area that is under right windows

Expected behavior
Resizing should be blocked the moment when you can't shrink down left window any more

Screenshots

In this example, you can't click github logo, when focus is on left window
