HTML Filtering breaks Font Awesome (monkeytype.com) #295

I have encountered this on multiple sites, but https://monkeytype.com is a good example. When HTML filtering is enabled, Font-Awesome (CSS) breaks.

HTML filtering enabled (arrow shows where icon should go)

Many thanks for your report 👍 👍

Unfortunately, I cannot reproduce this. In the HTML code there is only one line with crossorigin/integrity attributes. In this line (Font Awesome) the attributes are removed correctly.

HTML filter disabled:
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/5.15.1/css/all.min.css" integrity="sha512-+4zCK9k+qNFUR5X+cKL9EIR+ZOhtIloNl9GIKS57V1MyNsYpYcUrUeQc9vNfzsWfV28IaLL3i96P9sdNyeRssA==" crossorigin="anonymous" />

HTML filter enabled:

You can try a new Firefox profile (about:profiles -> Wiki) to see if the problem occurs there as well.

Can you give me another website where this happens?

I am exceptionally confused now. I disabed and re-enabled LocalCDN on monkeytype and it fixed it. Also same trick appeared to work for player svg icons on yugenani.me disappearing.

But it's fixed I guess.

Hmm, okay that sounds strange. Disable and enable is not a good solution.

Have you tested this with a fresh Firefox profile?

No i haven't yet

If this occurs again, it's necessary to analyze this in detail:

• Which Firefox version (Normal, Beta, Nightly)?
• What other extensions are installed?
• Is there a user.js?
