I feel like this actually would have worked had the map been on Phazon Core. ...problem is, the Metroids wouldn't act like that if the map were on Phazon Core.
Judging by the videos/pictures people have shared, this is done without ever transitioning. The room doesn't even show on the map in some of the pictures, so it's never been transitioned to. That exact clip happening while the map is on Phazon Core could actually be all that's needed? I don't know.

It's probably worth mentioning this happened after like, 2 minutes of picking around at the door. Fairly reproducible.
