> I have a simple Cordova 1.7.0. test app that just handles mouse events an=
d logs event target (attached). I found out that mousedown and mouseup even=
ts are fired twice. First time they are fired in code by C# InvokeSimulated=
MouseEvent function and the second time by WebBrowser control itself. That =
leads to event handlers also to be called twice for each event.
> I found out that the second time WebBrowser fires events because native T=
ap event is not prevented. So I added tap handler that prevents event bubbl=
ing in order to illuminate unnecessary event firing:

> In this case events are fired only once, but I have the following issues:
> a.       After clicking on input field it is highlighted but virtual keyb=
oard is not opened.
> b.      Play button of audio element becomes not clickable.

> It seems that all events are fired correctly but there are some little di=
fference between system and Cordova events (see below):=20
