<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: Take 'parent' into account when checking for terms with duplicate names.
Terms with duplicate names are not allowed at the same level of a
taxonomy hierarchy. The name lookup introduced in <a href="https://core.trac.wordpress.org/changeset/34809">[34809]</a> did not
properly account for the 'parent' parameter, with the result that
the duplicate-name restriction was tighter than intended (terms
with duplicate names could not be created at different levels of
a single hierarchy).
Props mikejolley.
