From Cynthia: I think this doc should provide more detail here. What events do we think are typically ignored to trigger this statement being present? Assigning this to David for his perspective. 32189 1 dbolter 2010-02-16 15:43:34 +0000 I don't think we can be exhaustive here but one example might be events that are happening on an unfocused browser window. Maybe we could leave this section out or say something like "when filtering/throttling events browser developers should strive to do this in an interoperable way." 32757 2 andi.snowweaver 2010-03-02 15:33:57 +0000 Leave this text in and add the example David provided. Cynthia to check with the narrator team and provide a second example. 35200 3 andi.snowweaver 2010-04-21 20:50:46 +0000 Added the example of events in an unfocused window. Assigning to Cynthia to check with the narrator team and provide a second example. 42436 4 dbolter 2010-11-11 15:22:46 +0000 Another example is if there is a node removal, followed by the parent node removal... you could just create an event on the topmost parent removal. 42457 5 andi.snowweaver 2010-11-11 22:23:15 +0000 Modified from: For simplicity and performance the user agent MAY trim out change events for state or property changes that assistive technologies typically ignore, such as events that are happening in a window that does not currently have focus. to: To improve performance on APIs that use a broadcast event mechanism, the user agent may trim out change events for state or property changes that assistive technologies typically ignore, such as events that are happening in a window that does not currently have focus. On other APIs that use a subscription-based event mechanism, user agents should allow assistive technologies to subscribe to any event, and should not trim events.
