Dropdowns misbehave when inside Popups

Bug Report

Steps

1. Place a <Dropdown /> inside a <Popup />, with a <Button /> as trigger
2. Click the button (pop-up should open)
3. Click outside the pop-up (it should close itself)
4. Open the pop-up again
5. Open the dropdown
6. Click outside the pop-up

Expected Result

The pop-up should close.

Actual Result

The pop-up stays open. Only the dropdown closes. Clicking again outside will leave the pop-up open. The only way to close it is to click the button again.

Version

0.81.1

I think there is a bug which causes the appropriate handlers of the Popup to be overridden by the ones provided by Dropdown if they are not in separate event pools.

@milkers a possible solution to that would be to pass eventPool e.g. set to testing as a property of the Popup. I am still to find if there is more to that (if there is an actual bug).
