Posting this here, in case it got lost in some form. Also checking if it was fixed in any particular update...

Twitch Clip of this happening.

tl;dr: If you swap the config to "EXACT" Mode, and shut a door on yourself just right, you will VERY slowly clip through the door, or even get stuck in it altogether.

Known issue caused by differences between the APIs blocks use for suffocation/hitboxes in 1.12 and 1.14+. I don't really have a good idea of how to fix it but will leave open for reference.

Maybe this could be a "Help Wanted" issue, as well.
