A11y best practice: Landmarks should be unique

[Joel-Levi]

Following this pull request

There are now 2 aria live regions with role='region'

This violates the following best practice rule:

Rule: landmark-unique
Impact: moderate
Ensures landmarks are unique (https://dequeuniversity.com/rules/axe/4.8/landmark-unique?application=axeAPI))

The landmark must have a unique aria-label, aria-labelledby, or title to make landmarks distinguishable

While it is not strictly required, it is considered a best practice, I found out about it because I run chai a11y axe

Hi @Joel-Levi!

Thanks for report. Indeed, the role=region attribute should not be set there, so your tests were correct. We discussed it, and we'll remove this attribute in this PR.

Let's know in case of any further issues.
