Keyboard event not reaching broadway if embedded in an IFrame
When an application is drawn to broadway and the broaday output in included in an IFrame like
<html> <body> Broadway in IFrame <iframe src="http://localhost:5000/" width="2048" height="2014"></iframe> </body> </html>
Then the keyboard event don't seem transfered to the broadway IFrame and are ignored. You can compare how gnome-builder behaves for example directly on broadway URL or through this IFrame. This is quite annoying for Eclipse Che for instance, where we would like to offer Eclipse IDE over Broadway as a possible editor, but since Che includes editors in IFrames, keyboard is not usable at all (not very practical for an IDE or a text editor). It could just be that broadway widget should claim focus.
