Instantiation of convex polyhedral region seems to not work sometimes

1.20.5/6

Describe the bug

I'm not sure what's causing said bug, but as stated in the title, sometimes when instantiating a convex polyhedral region, and then using said region in an EditSession or something (I used EditSession#setBlocks), the blocks aren't properly modified. This is because the region, while it has all its vertices, doesnt have all the blocks that it should have - see this (me discussing the issue on Discord) for more info.

To Reproduce

1. Try to instantiate 2 convex polyhedral regions back to back.

Expected behaviour

It should populate the region with all the blocks, instead of just the vertices.

Screenshots / Videos

I know this doesn't show much, nor is it easy to see really, but this is the same screenshot I put in the Discord when discussing it. Check the link above that goes to the Discord for more context here.

Anything else?

Try on the latest version, There have been some changes related to region block setting

Seems to still be an issue with the latest snapshot

[dordsor21]

Is it definitely with exactly the same order of setting the points, etc. (between WE and FAWE)? There are no differences in the region classes

[cheeezburga]

I'm using a different set of points with each test that I do, but yeah the region still (seemingly at random) sometimes doesn't initialize properly. Like when I set the blocks of said created region, sometimes it fills them all properly, and other times it fills only the vertices, and other times it fills (again seemingly) random blocks. I haven't been able to recreate this on WE but I'll give it another go later
