Good observation Mytran. Yeah, that wall looks to be wild or modifiable given it's different configurations. Do you know offhand if there were any episodes where we were shown the version that sticks into a corridor and in the same episode see characters walk that same corner?
My episode notes have yet to be unpacked, but I have a feeling that it only happens once, in the early part of Mirror Mirror
. Even then, we don't really see that much of the offending parts of the Transporter Room, a bit of squinting might get us though that one.
