 Testing again the proposed patch, turns out the `aria-modal="true"` added
 to the media dialog in [45572] / #47145 prevents the ARIA live regions to
 work as expected. For example with Safari + VoiceOver, the live regions
 are ignored and the `speak()` messages are not announced. See the attached

 This is the intended behavior of `aria-modal="true"` which is meant to
 hide from assistive technologies any content that lives outside the
 element it is applied to.

 Given the current implementation of the `speak()` ARIA live region, `aria-
 modal="true"` can't be used. I removed it from the latest patches.

 [attachment:"47146-test.diff"] is for testing purposes: it logs to the
 console the spoken messages.

 [attachment:"47146.4.diff"] looks good for commit to me.

 Test with a good browser / screen reader combination e.g.:
 - Safari + VoiceOver
 - Firefox + NVDA
 - Chrome + JAWS

 - search for attachments in the media modal dialog or in the media library
 - check search results are announced
 - in the media modal: when the search returns more than 40 results (40 is
 the default limit) for example searching for `jpg` assuming you have more
 than 40 jpg images:
   - the first message is `Number of media items displayed: 40. Scroll the
 page for more results.`  (*note 1)
   - scroll the page and a second message announces the new number of

 Note 1: as mentioned previously, cropped images produce a mismatch between
 the "per page" parameter and the actual number of results. For example
 when there are 2 cropped images, the message will be:
 `Number of media items displayed: 40 ...`

 This should be addressed separately.
