Regression: lapce now fails to load any editor fonts, falls back to not-monospace/varied glyph width font

[ell1e]

With the recent bigger lapce update, I think the one to the different UI toolkit, it now fails to load any editor fonts. No matter which font name I try, none of them is applied. (It also doesn't even tell me that it failed, but I can see so since I know how the fonts are meant to look like.) However, it also falls back to not-monospace/varied glyph width font for the code which makes this more than a cosmetic problem and actually turns the editor somewhat unusable.

I believe this is related to RazrFalcon/fontdb#78 and have put together a proposed fix in RazrFalcon/fontdb#79
