Invalid font-family for editor

[BramVer]

I am experiencing an issue where the font for the editor is by default always set to an invalid value, instead of the font I specify in the settings. This is not the case for the preview font-family, so it's not as if the font could not be found or is provided incorrectly.
The value provided is always the following:

font-family: MarkdownEditor__codeEditor___browser-components-, Monaco, Menlo, "Ubuntu Mono", Consolas, source-code-pro, monospace;

This issue was introduced in the previous version (0.8.18).
Even after upgrading to the newest version which supposedly fixes being able to set fonts from settings.

OS: Arch Linux
Version: 0.8.19-1
Package: https://aur.archlinux.org/packages/boostnote/

Settings:

Issue:

Any idea on what's going on?
So far I've been able to deal with it by opening the developer tools and changing things there, but I shouldn't have to do this each time.
