Specification bug for single document suggestion NXQL query and Page provider

In the Studio online documentation of the Single Document Suggestion widget, it is documented that:
single document suggestion -> NXQL Query says:

This property is ignored if a Page Provider name is given

single document suggestion -> Page Provider says:

If no name is defined, a default page provider is used.

Thus, as a default page provider is automatically provided, the NXQL query is systematically ignored.

A workaround is thus to provide a page provider
Expected: the behavior should rather match If no name is defined and no NXQL Query given, a default page provider is used.
