Description of the issue:
Brave Shield seems to block font changes from CSS
Exact URL of the website in question:
https://speeddemosarchive.com/quake/
Effects the menu side-bar and some other pages on the site.
Did the issue present with default Shields settings? (yes/no)
yes, fonts look incorrect
Does the site function as expected when Shields are turned off?
yes, fonts look correct
Did some more testing with Shield settings and changing “block fingerprinting” to disabled ‘fixed’ the issue.
Also the fonts seem to look correct on the Andriod app with standard fingerprint blocking if that helps.
It seems the issue was fixed? The fonts are now correct with default shield settings
