PurgeCSS does not purge class names that appear in HTML comments

[mpare1987]

I noticed recently that PurgeCSS does not remove display utilities if the class name appears in an html comment or in the text of a node.

For example:

<!-- Requirements grid -->
<h1>Requirements grid</h1>

Either of the above will result in the "grid" display utility not being purged.

Is there any way to configure PurgeCSS to be a bit more selective about where it purges from? I'm integrating tailwind ino a legacy app, and am trying to reduce the risk of unintended style collisions.

Any and all help very much appreciated!
