Cannot catch drag events in HTML container

[Robert Schroll]

HTML running in the ubuntu-html5-app-container cannot detect drag events. There seem to be two related problems, demonstrated in the attached test case. First, the mousedown, mouseup, and click events are all emitted at the same time, rather than when the events occur. Second, these events are only emitted if the mousedown and mouseup events happen in the same location.

I'm guessing the problem is that the QML shell is holding onto these events to figure out if it needs to do something with them. It shouldn't in this case -- the events should be passed on to the WebView as soon as they're received.

This is seen on 12.04 using the SDK Team PPA.

Presumably, this is the root cause of bug #1293898.

I think the events are being captured by QML.

I assume ubuntu-html5-app-container will be moving to Oxide at some point. That may end up solving this problem -- in some informal testing, I've seen that Oxide seems to behave sensibly w.r.t. drag events on the desktop.

Marking as fixed released, and tested on krillin/mako.
