<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Taxonomy: Ignore cached term value when it doesn't match the queried taxonomy.
When a cache entry is found that matches the requested `$term_id`, but
doesn't match an explicitly provided `$taxonomy`, that cache entry
should be ignored.
