@tempertemper can we just check whether this is a false positive caused by the use of Portals here?

[edleeks87]

@tempertemper any thoughts on the above

[Parsium]

After discussing with @tempertemper, we noticed that Toast has no semantic meaning, just a <div> with text content.

Since Toast is designed for status announcements or alerts, adding a role of "status" or "alert" should address the semantic issue, which may also resolve the axe violation.
