Nearby events dashboard widget "city updated" speak message announced on page load

[afercia]

Just noticed (a bit late...) that when loading the dashboard page, the Nearby events widgets renders its template and also sends to the ARIA live region the assertive message "city updated"

this is not ideal on page load, since users haven't taken any action and there's no need to confirm an action that hasn't happened. It's also confusing and a bit annoying hearing that message every time the dashboard screen is loaded.

42037.diff​ checks for initiatedBy to send the "city updated" message. This way, the message should be announced only when the city gets updated by users. Not sure if it's the best option or there are better ways. Also, I guess the similar unknownCity doesn't need the same check. /cc @iandunn (hey)

Good catch!

I was able to reproduce this before applying 42037.diff​, and applying it fixes the issue for me. The message is still announce when manually changing the city, too.

The diff itself also looks good, so I'd say go ahead and commit it :)

@iandunn Thanks!

In 41682:

Accessibility: Improve the Dashboard Nearby Events widget wp.a11y.speak() messages.

Avoids to announce the "city updated" message on page load.

Fixes #42037.
