[TIMOB-17266] Popover: passthroughViews only work when the popover is first shown. Fails on subsequent tries.

REPRODUCTION: Run the code below in the iPad simulator. RESULTS: Click on the "Open Popover!" button to show the popover. Click on the "Click Me!..." button. The popover does not dismiss. Dismiss the popover and click on the "Open Popover!" button to show the popover again. Click on the "Click Me!..." button. The popover is dismissed. EXPECTED RESULTS: The popover should not be dismissed when clicking on a passthrough view. OTHER NOTES: If the contentView is a Window, the popover does not display properly the first time. TEST CODE: {noformat} var win = Ti.UI.createWindow({backgroundColor: 'white'}); var button2 = Ti.UI.createButton({ title: 'Click Me! I do nothing!', top: 25 }); win.add(button2); var contentWindow = Ti.UI.createWindow({ backgroundColor: 'green', title: 'Popover' }); contentWindow.add(Ti.UI.createLabel({text: "I'm a popover!"})); var navWindow = Ti.UI.iOS.createNavigationWindow({window: contentWindow}); var popover = Ti.UI.iPad.createPopover({ //contentView: contentWindow, contentView: navWindow, passthroughViews: [button2] }); var button = Ti.UI.createButton({title: 'Open Popover!'}); button.addEventListener('click', function(e){ popover.show({ view: button }); }); win.add(button); win.open(); {noformat}
