Close/clear a chrome extension notification while notification panel is open

References: https://developer.chrome.com/apps/notifications I am using the chrome.notifications.create(string id, object options, function callback); to create a chrome notification. ``` var id = 'list'; var options = {}; options.title = 'test'; options.iconUrl = 'notification_icon.png'; options.type = 'list'; options.message = "test"; options.buttons = [{title: 'test'}]; options.items = [{title: 'test', message:'test'}]; var createCallback = function(notificationId) { console.log(notificationId); }; chrome.notifications.create(id, options, createCallback); // returns 'list'; ``` This creates a notification as expected. All working correctly. I then call chrome.notification.clear(string id, function callback); ``` var id = 'list'; var clearCallback= function(wasCleared) { console.log(wasCleared); }; chrome.notification.clear(id, clearCallback); // returns true; ``` This does clear the notification. All working correctly. EXCEPT it does not clear the notification out if the notification panel is open. This is not a major problem 99% of the time. Until I implemented the button code within the notification. Using chrome.notifications.onButtonClicked.addListener(function callback); On click I am calling the clear notification panel code, and it reports back as it has been cleared. ``` var onButtonClickedCallback = function (notificationId, buttonIndex) { console.log(notificationId, buttonIndex); if ( notificationId == 'list' ) { chrome.notification.clear(id, clearCallback); // returns true; } } chrome.notifications.onButtonClicked.addListener(onButtonClickedCallback); // onClick it returns 'list', 0 ``` But I am looking right at it.. Once the notification panel closes and opens again, I can confirm it has actually gone. But obviously since I am clicking a button on the notification, the panel is open, but it does not clear away as I would have liked. All this is running in an extension background without the persistence: false property (so the script is always loaded, and since I can see the output, I know the functions are being called). Have I overlooked something? I do not see any functions that deal with closing the notification panel. So as far as I can tell, I am clearing the notification but the panel is not updating it's display. I am using Chrome 37.0.2019.0 canary on Win8 If anyone can suggest something I may have missed, I would be greatful. My google searches reveal people having problems with the HTML notification.
