This works as described!

The comments are visible (and posts are comment-able) on metered posts when the reader can still view the full post, but the comments and comment form are hidden when they can't see the full post.

I tested this both with the inline and overlay gate, and with commenting open to all readers and limited to only users who were already registered on the site 🚢
