Is this Landmark Best Practice Issue accurate, or did axe make an overcall?

[goodwitch]

Issue: I ran axe on this page http://test.austinfree.net/ (as a Judge for Knowbility's AIR competition).
The following Best Practice issue is being thrown: 'All page content must be contained by landmarks"
on the video player that is within an iframe that is within <main>.

Expectation: I was wondering if the iframe inside main was enough to count this player as being within a landmark, or if additional landmark need to be added within the iframe.

axe-core version:4.0.2
axe-extension: version 4.6.0

Browser and Assistive Technology versions:
Firefox: 83.0

For Tooling issues:
- Platform:  Mac 11.0.1

You are correct. That needs to be fixed. Looks like we didn't properly fix #2330 @straker. Sorry Glenda, we'll get it resolved ASAP.

@WilcoFiers Any update to this? We're running into the same issue with YouTube embeds elsewhere. Thanks.

Validated on test page: http://test.austinfree.net/
able to reproduce using axe-expert, seeing Best Practice issue on region saying "All page content must be contained by landmarks"

and seeing the fix in the latest develop branch code- axe-core (9th July,2021)
not seeing any issue either violation or Best-practice on region within iframe that is within

.
