11711	tag_id Doesn't Work in WP_Query	miqrogroove	ryan	"WP_Query::parse_query() stores a value in {{{$qv['tag_id']}}} but it does not query the tag name, and WP_Query::get_posts() never checks the tag_id value.  Thus, this variable does nothing.

I noticed this while working on #10640.  The tag_id variable could be useful for the specific purpose of URL shortening where long tag slugs may be problematic (e.g. micro-blogging)."	defect (bug)	closed	normal		Query		normal	duplicate
