The drive will only remap bad blocks when you try to write to them, so
if you haven't written to them then it is no surprise that they aren't
going anywhere.

If the drive is actually returning bad data rather than failing the
read outright, then the only thing you can do is to have btrfs
duplicate all data so if the checksum on one copy is bad it can try
the other.
