Changes between Initial Version and Version 1 of Ticket #30788, comment 5

initial	v1
1		Patch uploaded which allows `wp_match_mime_types()` to deal with an array of comma-separated MIME types (effectively a double nesting issue). This appears to fix th~~is problem but the code here is quite convoluted and I would like a second opinion on~~ this solution. It is also unclear to me why the original code added a third regular expression to match the main MIME type pattern un-anchored, so I have removed this.

3	3	Also, because the screen filter selection value may now include a comma, I had to revert to the original solution presented in #30123, namely using `esc_attr()` rather than `sanitize_mime_type()` when preparing links for the filter dropdown. This seems more correct in any case.
