I noticed this morning that links to comments in the form
https://SE-site/questions/[question-id]/#comment-[id_of_comment]
do not work anymore (at least on Firefox and Chrome browsers).
These links used to trigger the default scroll to element with id behavior, but a CSS rule display: contents;
on these elements breaks the feature (since they don't have their own box anymore, browsers can't scroll to it).
Example
FF37+ and Chrome 58+ with Enable experimental Web Platform features
flag.
Note:
Links in the form https://SE-site/posts/comments/comment_id
do work as intended thanks to js, so this doesn't affect links in in-box messages.
display: contents
rule : As of today only FF37+ and chrome with Experimental Web Platform flag.
