Share snapshot - embed code not removing menus

I've just upgraded our environment from 5.5.2 to 7.4.0, and find that the embedded iframe short URL includes the Kibana menu/frame. Is this a bug? Am I doing something wrong? Is this not recommended practice in v7 ?

Wondering if anyone else is seeing this behavior? If anyone has a suggestion or recommendation?

Suggestions here on the issue we're seeing? Any advice or insight greatly appreciated.

It looks like this might be a regression as it was recently reported and being tracked here: https://github.com/elastic/kibana/issues/50107

Yes - I reported it as a bug when I got no response here.
