Hi, In ยง4.6 Activating a notification, there's a note that currently reads
"User agents are strongly encouraged to make window.focus() work from within the event listener for the event named click as a means of focusing the browsing context related to the notification." This note assumes that the UA doesn't automatically focus the browsing context when a notification is activated. (Safari on OS X is one example of a UA which does this.) The note should be adjusted so that readers understand that calling window.focus() may not be necessary on some combinations of UA and system notification service. Ted
