It should do both a and e tags, but that's not going to prevent clients that don't handle things well (at the very least, ue NIP-31) from not showing things out of context.
the event has the context, some clients are just not displaying it.

Ah ok. I was wondering this after when i paid closet attention to what i was signing. Maybe a workaround would be to include a link to the video page at the end of the comment?
Agree that the context is there, the e tag is a pragmatic way of dealing with it on most clients for the time being.
It also addresses the issue of outdated comments if the publisher ever updated the replaceable event.
the e-tag won't make it appear in tons of clients, including Damus
Just fixed this to use both a & e tags
