My red heart emoji (❤️) looks weird in #Firefox

This has been the case for quite a while now and I cannot for the life of my figure out why that is. I never explicitly made it this way.
It's only in Firefox and a machine with pretty much the exact same #NixOS config does not exhibit this issue.

I tried clearing unused fonts out of \~/.local/share/fonts/ (no emoji fonts remain) and updated the fc-cache but it didn't help. (Obviously I restarted Firefox.)

Any ideas?

After a bit of confusion, I found out why my #Firefox was being laggy on some website despite me turning off Javascript.

Turns out I had set layers.acceleration.disabled while debugging V-Sync.

What this setting does is effectively disable hardware acceleration for a core component of page compositing; making everything laggy.

Mess with settings in a dedicated guinea profile people!
