Modules refuse to move or move to random places upon save

I am still getting this issue in 2023… Some sites - at some point something goes wrong - and modules continue to jump up / down pages when saving… I simply cannot get modules to stay or move to where I want them to be.

When I add a new module and drag it into place, it appears at the top or the bottom.
Has anyone experienced this? This is probably the 3rd BB site I’ve had this happen on, but when it does happen it is the absolutely most frustrating experience to deal with.
