Font of the line number does not scale as the font size increases / decreases.

[mhaz]

I'm displaying the line number with display-line-numbers-mode.
I've noticed that when I scale up up or down the font size, the size of the line number in the leftmost column stays unchanged.
This does not happen with the other (builtin) themes I tried.
Is this an issue of moe-theme?

Cannot reproduce the issue you described:

Tested on GNU Emacs 27.1 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.22, cairo version 1.17.3) of 2020-08-29

Have you ever tried them under emacs -Q?

With emacs -Q:

The font of the line scales.
Now I install moe-theme and load moe-dark:


The font doesn't scale anymore.
I'm using GNU Emacs 26.3.
