Update aria-level
on heading
mapping to reflect UIA limitation
#1757
Comments
https://w3c.github.io/aria-practices/#structural_roles restricts the use of aria-level to the values 1-6. I did not find this restriction in the ARIA specification itself. This should definitely be unified. If aria-level is really limited to 1-6 for headings, then this issue and the Chromium bug would be solved. |
Agree to limit aria-level for heading — not for other roles that use
aria-level.

The spec now has a note about this. |
We received a Chromium bug where
aria-level
values > 9 onheading
do not work.A commit in 2014 added this limitation due to UIA restrictions. UIA maps the
aria-level
onheading
to the StyleId_Heading value, which is limited to 1 through 9.Suggesting an update to the core-aam mapping for
aria-level
onheading
to more clearly reflect this value range limitation or link to the StyleId_Heading documentation.@joanmarie
