To recreate:
1 - have LinkerModule set to First Match
2 - have a bib with its author linked to an authority
3 - duplicate that authority, confirm that an authority search for your author
brings up two identical authorities, one linked to your bib
4 - merge the two authority records, telling Koha to keep the newer of the two
(the one not linked to your bib)
5 - search authorities for your author again, confirm you see just one
authority and it's not linked to any bibs
6 - reload your bib, see the 100$9 contains the number for the authority you
deleted in the merge
7 - edit your bib to correctly link it to the remaining authority
8 - set LinkerModule to Default
9 - repeat steps 3 and 4
10 - see your remaining authority is linked to your bib, the bib has the
correct authority number


I'm not able to replicate this in master. I'm not sure what changed from 21.05.
