#42104 new defect (bug)

Tax query transformations unintentionally filtered by 'terms_clauses'

Description

Since [40918] tax queries are transformed using WP_Term_Query. That's nice because the previously uncached query is now cached.

This however raises a backward compatibility issue as all existing filters applied to a term query are now unintentionnally applied to the tax query transformation.

The same kind of issue was raised by [38667], when the usage of WP_Term_Query was introduced in wp_get_object_terms(). However in this latest case, the unique presence of $args['object_ids'] in the arguments, not interpreted by WP_Term_Query, allows to differentiate term queries fired wp_get_object_terms(). There is no such unique argument which could serve the same purpose for the tax_query transformation.

I suggest to add a dummy parameter to the arguments of the query which would not be interpreted by the core and would only be useful to plugins to distinguish this query from others.
