Yes, both Dominic and I pointed that out earlier in the thread.
My mumblings about events for relationship changes were because I took
Dominic to ask further if there was also a RELATION_CHANGED event
associated with changes in aria-describedby, specifically if there was a
RELATION_DESCRIBED_BY_CHANGE event. There isn't AFAIK. If I mistook
what Dominic was asking, perhaps he could clarify.
Otherwise, if aria-describedby changes, then
- the accessible description is updated, and platforms will fire a
'description-changed' event as documented in the accessible name
calculation document. [1].
- platforms will update the relevant 'describedby' relationship if they
expose any, but no 'relationship-changed' event will be fired for this
update. For example, IA2_RELATION_DESCRIBED_BY and IA2_DESCRIPTION_FOR
modifed to reflect the change,
