759833 - ARIA documents should fire document loading events

Status: RESOLVED FIXED

Description

[alexander :surkov]

We were asked to fire document loading events on ARIA documents (like role="dialog"). 

For the start we can fire document loading complete when ARIA dialog appears in the tree. We can delay an event while ARIA document has aria-busy.

ignore aria-busy stuffs, they complicate the logic and no evidence the web really needs it

kind of funny we do it for dialogs too, but I guss its sort of reasonable

it'd be nice if you didn't add to the event firing based on nodes.  I'd be sort of fine with a temporary inline function that got the accessibles node and fired the event.

it'd be nice to have one for ria documents in case logic changes somehow one day.

yep but we were asked for this and after all we do that anyway if you apply proper ARIA role to document.

I wouldn't do this time since coalescence happens by DOM tree. I need to reorg all this code one day.
