• Photo 1: A tight window width, no sidebar and no hamburger menu (bug)
  • Photo 2: Widened a little bit, sidebar shows up, hamburger menu gets hidden (intended)
  • Photo 3: Narrowed, sidebar hides, hamburger menu shows up (intended)
To reproduce, increase/decrease the window/canvas width slowly/carefully in 1 px increments/decrements.
I don't have exact window resolution measurements, but it's a narrow width difference that triggers the bug (1-2 px).
