It isn't ideal since what should happen is that the bias is kept on
while any paths are active (not just digital ones) but it shouldn't
cause any problems since all that should happen is that the checks
for bypass paths being active will just always return false.  I'll
the patch - when the core becomes more capable the patch can always be
revisited.
