Subject: Allow "class" attribute on the "a" tag in sanitization (#3623)
X-Git-Url: https://git.xn--scling-oua.cat.family/?a=commitdiff_plain;h=6bd6dcf6df37dea077c4c6af84d979a49dd058db;p=mastodon.git

Allow "class" attribute on the "a" tag in sanitization (#3623)

This preserves `<a ... class="u-url mention">` from other Mastodon instances.
