Thanks for the report. It's probably a more general issue with language subtags.

For this vocabulary the fr-fr Tags work in the tabs, but not in the concept page title.

In this example the tabs do not work either.

The difference between the two is, that in the first example the tags are defined as "fr-fr". In the second example they are defined as "fr-FR".
