Problem of click event bubbling (is this spec or bug ?)

[8823-scholar]

Hello.

I Have a probrem of click event bubbling.
Is this spec ? or bug ?

case 1

click event reach to under other instance when exportRoot not have click event listsners.

case 2

click event not reach to under other instance when exportRoot has click event listsners.

cause code

Container._getObjectsUnderPoint method considers that container has click event listsners.
if container not have click event listsners, this method ignore not click event listsner children.

I think that click event should not reach to under other instance in any case.
What do you think ?
