potential fonts module issue

I'm posting a little tentatively on the off chance someone else has insight that'll save me some debug time this evening. I was putzing around with the fonts module to test it out and copied in my font list from nixos (which included a handful of individual fonts, mostly code/mono, powerline, corefonts and vista-fonts).

It looked like I had this working, but a bit later I noticed Arial showing up on a few sites where it wasn't before (google.com, stack overflow). I haven't successfully fixed or debugged it yet, but I can imagine at least a few ways it could go awry. Example:

I have an older macbook at home that is also on Mojave; I compared the /Library/Font directories just now and see what is causing the trouble. The one having trouble was missing (among a few others) a plain Arial.ttf that was present on the other system, so I guess Safari was substituting Arial Black.ttf in its place.

I copied this over and it started working fine again.

Reading around a bit turned up some suggestions that fontrestore is better at getting rid of new fonts than it is at restoring missing ones, so I suspect that corefonts' arial got linked over the existing copy, and then fontrestore removed the unrecognized copy on a subsequent rebuild.

We actually only run fontrestore in dryrun mode to see what it would remove. Not sure if we can fix this without removing and re-adding the fonts every time.
