Re-enable ContentViewPopupZoomerTest

PopupZoomer will stick to the initial container view and will refuse to switch
when ContentViewCore.setContainerView() is invoked. This is by-design as we
never intended to support disambiguation popup for WebView or fullscreen video.

Removes @RerunWithUpdatedContainerView and re-enables the test.
