detect that swipe was over container

[Yehuda Katz]

Hello,

I have my own scrolling for container, everything worked fine until: I had popup with scrolling over background which could be scrolled as well ?

The issue is obvious: while I am scrolling popup, the background is also scrolling.

Of course I can improve code and check that pointer down was over container but there are over elements which grab mouse down event and prevents it to be passed to the bottom container.

Is there any pattern to resolve this issue?

Thanks
