Description
Following a chat with Tommy, it turns out that v4 was also susceptible to block elements that are part of a revision being deleted with the garbage collection. This affected Matrix, Neo, and Super Table blocks.
This fix has two parts: the first commit ensures we don’t delete blocks that any soft-deleted block elements that are part of a revision are truly skipped. The second commit handles deleting structures in a way where we first check if the elements that are part of that structure are not part of a revision. This ensures the neo blocks that are part of a revision don’t get deleted via garbage collection.
The 2nd and 3rd commits can be merged into v5 too. Please LMK if a separate PR should be raised for v5.
