`[[A|{{comment|text|comment}}]]` doesn't work properly in ruwiki: `{{comment}}` template contains a `<templatestyles>` tag, but no template styles are applied.
`<templatestyles>` expands into this code:
```lang=html
<style data-mw-deduplicate="TemplateStyles:r93295199">'"`UNIQ--templatestyles-00000001-QINU`"'</style>
```
(note the [[https://www.mediawiki.org/wiki/Strip_marker|strip marker]]).
`{{comment|text|comment}}` works fine, and `<templatestyles>` expands correctly:
```lang=html
<style data-mw-deduplicate="TemplateStyles:r93295199">.mw-parser-output .ts-comment-commentedText{border-bottom:1px dotted;cursor:help}@media(hover:none){.mw-parser-output .ts-comment-commentedText:not(.rt-commentedText){border-bottom:0;cursor:auto}}</style>
```
This is because the template is used inside a link. The point of using this template inside a link is to provide a tooltip other than the standard tooltip for links.
