withYHistory undo will remove blocks with remote changes in them

[Bartlett-Will]

As stated in the title, there are some weird behaviours happening when differentiating remote and local changes. If a remote change is made inside a block that has formatting, and a local user undoes edits around the remote change inside the block, the formatting is removed from the remote change. Similarly if you create a new block locally and there is a remote edit on the new block, the local user can undo the new block and with it the remote changes.

This is an edge case for sure but I thought it is worth documenting.
