Test: ARIA alertdialog role must use document mode
Current support: partial (9/9)
This test ensures the alertdialog role does not invoke application mode in screen readers. The default mode (document) must be used. ARIA 1.0 had language for the alertdialog role that could suggest that application mode must be invoked. However, that language was clarified in aria 1.1.

Support tables
Assertions are conditions that must be met for the feature to be considered as "supported". Only "MUST" assertions need to be met for minimal "support". "SHOULD" and "MAY" assertions indicates support that goes above and beyond. Note that there is not an explicit standard that dictates these assertions, and as such, they are likely opinionated. Minimal support reflects that the structure, relationships, and functionality of the feature are conveyed and operable by assistive technology rather than minimal conformance to any specific WCAG SC. As such, a feature might not meet all "MUST" assertions but still be usable (potentially frustratingly so).
