narrow: fix flaky behavior described in issue6150
This has been plaguing the CI for a good while, and it doesn't appear to have
an easy fix proposed yet. The solution in this change is to always do an
unambiguous (but expensive) lookup in case of comparison. This should always
be correct, albeit suboptimal.
