Edit screen Custom Theme too small width

Due to a translation error in the invoice/quotes I wanted to inspect the custom theme code. I’ve noticed that the edit screen has shrunk to a too small width in the current version 21.3.1 (stand alone macOs). see attachment. @Ludos, please fix. Thank you.

I’ll mark this as a bug.

Meanwhile, @IntoTheMirror, you can still access and edit all theme code using arrow keys or your mouse/touchpad while your cursor is in the Template field.

I am also facing the same problem on Windows 10.

Fixed in the latest version (21.3.3)
