Tags meta box: add a `button` ARIA role to the tag cloud links
|Reported by:||afercia||Owned by:||afercia|
For better accessibility, the tag cloud links in the Tags meta box should be reported to assistive technologies as buttons.
They're not real links because activating them doesn't navigate to a new resource, instead it performs an action. The tag cloud is printed out in different contexts though so the ARIA role should be added just on the Tags meta box. I'd propose to check for the links href attribute, when it is set to #.
