Description

We had an a11y issue opened:
“Interactive component with ARIA role 'alertdialog' does not have a programmatically associated name”

This boiled down to the fact that we have an ActionableNotification with no title (just a subtitle). The ActionableNotification code ties the aria-labelledby to the title, so if you don't have a title, you end up with this issue.

It would be nice to have a bit more flexibility, so you could have a notification without title and not have an accessibility violation. Basically, fall back to the subtitle if there's no title. We'd need to add an id to the subtitle div and point to that in this case. (there's other options too of course, but that seems logical. Could also have a hideTitle or a separate prop for another aria-label)

We went ahead and added a title to our ActionableNotification for now to resolve the issue, but we shouldn't have to do that.
