Unfortunately I don't think there's any shell-language-level workaround.

You could try fiddling with the order in which the zle -F handlers are
removed and skip closing the descriptor in update_super_status, but it
will become complicated to keep track of the un-closed descriptors in
order to avoid leaking (i.e., never closing) them.
