Accessibility: Error and status toasts are not perceivable by screen reader users

Issue Summary

Error and status messages are not perceivable by screen reader users. Their descriptors do not describe them as error messages.

This is reproducible on Data Center: yes

Steps to Reproduce

1. Reproduce the error
2. Examine it with the devtools and see that it is not described as error and thus not perceivable by screenreaders as such

Expected Results

Error and status messages that are displayed visually should be marked with suitable roles and properties and can be determined programmatically, which means that the status messages are presented to users of assistive technologies (screen readers) without them receiving the focus.

Actual Results

Error popups appear as generic popups

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
