Nested toc produces multiply-defined labels in LaTeX output about sphinx HOT 4 OPEN

Just wondering but does this also happen with HTML? or is it only with the latex build?

Also, your fix makes builds nonreproducible due to the arbitrary order of a set. In addition, I'm not sure that it would work if you end up with nested labels that could then collapse to a top-label.

I cannot check this this week though so it'll need to wait a bit.

If the order is important, then how about something like

labels = ''.join(self.hypertarget(node_id, anchor=False) for node_id in {k: None for k in node['ids']})

I don't know if it also happens in HTML. I'll check when I get a minute.

I don't know enough to comment about collapsing.

I don't see it happening in HTML.

Thank you. This needs investigation on our side then to make the fix as smooth as possible.
