Message:

Taxonomy: Filter the arguments passed into wp_dropdown_categories() in the Categories post edit metabox AJAX request output.

This commit fixes a bug that caused differing dropdown results between AJAX & non-AJAX output, when using the post_edit_category_parent_dropdown_args hook.

(That hook is documented inside of the post_categories_meta_box() function, introduced via r33682 and #33026.)

Props obiplabon, birgire.

Fixes #44343.
