Does DNS-over-HTTPS get cached at the OS level?

🤔  I'm using Firefox for Mac. I'm curious does DNS-over-HTTPS get cached in the browser, or at the OS level?   i.e. ...

1. DNS is resolved in Firefox and somehow cached on the Mac (I could kind of doubt).

2. DNS is cached within Firefox, Firefox controls expiring cache, never touches OS.

Thanks!
