wikilinks_title_after_pipe unexpected '2' Error mixed markdown and wikilinks

[jfishe]

Explain the problem.
Since v3.1.12, pandoc markdown extension wikilinks_title_after_pipe does not parse mixed wiki and markdown links.

printf 'Messina ([2007](#ref-TSTF-475-Ar1))\n\n([[#ref-TSTF-475-Ar1|2007]])' | 
pandoc \
  --from=markdown+wikilinks_title_after_pipe \
  --to=markdown 

Error:

Error at (line 1, column 11):
unexpected '2'
Messina ([2007](#ref-TSTF-475-Ar1))
          ^

Expected response:

Messina ([2007](#ref-TSTF-475-Ar1))

([2007](#ref-TSTF-475-Ar1 "wikilink"))

Pandoc version?

v3.1.3 - v3.1.11.1 produce the expected response. V3.1.12 - v3.1.12.1 produce the error.
