Ah, right.

The other possible solution (that I mentioned, but didn't expand on) is
that we could just fix this in electric-pair without relying on
narrow-to-field.  That is, once electric-pair has found the matching
pair, we just look at the region between the two chars and see whether
they are part of the same field.  That should be reasonably fast, since
electric-pair already limits the range it's willing to search for a
pair.
