Not folding on deeper structures

[stuboydl]

I have a tree structure with a deep fourth (5th & 6th) level off the last third end node. Folding doesn't work on this level.

@stuboydl could you please provide the tree data so we can attempt to reproduce this.

if you are able to trim it down to just the part that breaks that’d be appreciated.

Perhaps this is similar to #15. We'd need to dive into the logic again cause it's been a LONG time since we worked on this 😂.

Also @alex-oser doesn't code anymore 💀
