Are tags renderred differently in questions and comments on purpose?
The editing help explains that comment formatting supports shorthand links, including:
[meta-tag:tagname]– link to the given tag's page. Link text is the name of the tag.
meta-tagonly works on meta sites.
Whereas such links are formatted with the
post-tag CSS class in posts, which styles them as tags, they are not so formatted in comments—instead just appearing as normal links; it is therefore not always evident that one is referring to a tag without explicitly stating
Please apply the
post-tag class to such shorthand links in comments.
