Comments left by mastodon do not get pushed to lemmy

### Quick summary

When leaving a comment to a WP post via mastodon, if that post has been federated to lemmy already, the WP comment won't be sent to the lemmy "community".

### Steps to reproduce

I opened this blogpost: https://dbzer0.com/blog/this-blog-is-now-federated-natively-to-lemmy/

It got federated to lemmy here: https://lemmy.dbzer0.com/post/31734668

I left one comment from lemmy, which federated back to WP

I then replied to that comment via mastodon: https://hachyderm.io/@db0/113503918837384265

The comment appears in wordpress, correctly threaded bellow the lemmy comment. However it does not appear in the lemmy community.

### What you expected to happen

Lemmy communities normally send through any comments received to all their subscribing instances. In mastodon it thus appears as if they're "boosting" all their comment. Something similar should happen in this plugin as well.

### What actually happened

The comment from mastodon does not sync to lemmy.

### Impact

All

### Available workarounds?

No but the platform is still usable
