Comment boosts not showing as comments

### Quick summary

I have a comment listed in the comments WordPress screen as approved. On mastodon.social it is a comment boost. I can't get it to show up on the front end.

The comment arrives as a "Response" and shows as a repost when it kind of seems like it should show as a comment. I think the issue is that comment boosts sits in a bit of gray area - is it a comment or a boost?

### Steps to reproduce

1. Comment arrives as "Response" type
2. Hmm... that's not showing up as a comment, just a repost icon

### Site owner impact

More than 60% of the total website/platform users

### Severity

Moderate

### What other impact(s) does this issue have?

No revenue impact
