Ogham Manor out of bounds glitch

If you roll at this section of ground your character will fall through the ground or fly a bit above the ground for a second. Seems consistent if the roll is near ending when you are on the spot. Found this by accident when mindlessly running its kinda fun to play with, anyone done this before? I'm not sure how to paste a photo but here's the screenshot: https://imgur.com/a/IX4PCBN

Heres one of me flying, you can get higher than this https://imgur.com/a/MGRFJVS

The entire layered section (idk what to call it) has edges that do this now that I have progressed further into this dungeon
