Changeset 30347 for trunk/src/wp-includes/taxonomy.php

Timestamp:

Message:

Flush cache for newly created term in _split_shared_term().

The term itself does not have any cached values yet, but in some cases the new
term's taxonomy may need its cached hierarchy to be refreshed as a result of
the term splitting.

Props jorbin.
See #30335.
