        [WML] WMLPageState is not allowed to store the active card, it needs to be done per document
        https://bugs.webkit.org/show_bug.cgi?id=28180

        Don't store the active WMLCardElement in WMLPageState, but in WMLDocument.
        Otherwhise this may lead to crashes related to intrinsic event exeuction.

        Unfortunately select elements aren't testable by the layout tests, so adding
        a new manual test reproducing the crash.

        * manual-tests/wml/select-onpick-event-crash.wml: Added.
