Code Editor 2: Clicking and dragging Split View button to split horizontally only works once, then RMB to split horizontally can cause issues with editor window

Description

When verifying #5235, I noticed that you're able to click and drag to create a vertical split several times, but clicking and dragging to create a horizontal split only works once. Also, if you click and drag to create a horizontal split and then right click the Split View button a couple of times (which should create horizontal splits too), it appears that the code editor window starts to shrink.

@stuckie these are both issues in CE2 using the Split View button but with different steps and outcomes, so I decided to separate them into two tickets.
