It's the first node that's not in the disallowedNodes AFAICT.

I wondered why the USB mappings don't suffer the same issue though. The
nodeChange() callback gets called with the correct value when editing
the mapping for a specific node, even though the node selector
definition and setting of disallowedNodes is the same as for the PCI
mappings.

Looking at Javascript backtraces, it seems like there might be some kind
of race going on (whether the me.getStore().load() for
PVE.form.NodeSelector finishes early or not), but not clue why it
happens for one, but not the other.

That said, adding a similar condition for the USB mappings would still
be good IMHO.
