The spec does not mention how to resolve a conflict if a document contains multiple instances of aria-modal="true"

Some ideas:

nested modals (a.k.a. dialog stacks) should probably be allowed
unrelated modals (one is not an ancestor of the other) should be considered in conflict, but how to resolve:
- Both are invalidated?
- latest in DOM order wins? WebKit currently behaves this way.
- Most recently shown modal wins? Probably difficult to implement as "shown" can be ambiguous.
- Highest modal in z-order wins? Also potentially difficult to implement.

The text was updated successfully, but these errors were encountered:

jnurthen added this to the ARIA 1.3 milestone

jnurthen modified the milestones: ARIA 1.3, ARIA 1.4
