Current behavior

I am seeing z-index and display: none problems with the markdown editor when in full-screen side-by-side preview mode.

I was able to change the z-index of the left side, some buttons, the sidebar and get it showing as I would expect, and turn off a display: none on the right side with the preview.

Before CSS tweaks:

Expected behavior

I expect the markdown on the left half and the preview on the right half of the screen without objects from behind showing on top of the editor or preview windows.

Minimal reproduction of the problem

Click markdown editor side-by-side button.
