In the footnotes at the bottom of a post, the numbers are not shown on iOS (multiple browsers), but the user reports they work correctly on desktop and I see them working correctly on Android. (I don't have an iOS device to test with.) On Apple iOS 15.3.1, the user tried with:

• Chrome 97.0.4692.84
• Safari (iOS v15.2.1)
• Firefox Daylight 96.0 (7403)

It's possible the problem is with iOS, but is there anything we can do to mitigate?

The ::marker psuedo-element only has partial support (MDN, WebKit Bugzilla) on iOS (webkit) browsers, so yes this is most likely a problem with webkit.

Reproduced in Safari on MacOS, so it's not just iOS.
