[NTG-context] error: (nodes): fuzzy token cleanup in whatsit node

[Sylvain Hubert via ntg-context]

Dear List,

I think I've just encountered a fragile bug. It is only reproducible
with exactly the same layout as the doc below. Any insertion or
removal of an item that changes the pagination would let the document
compile.

Could anyone reproduce or explain this bug?
