fix scroll event handling since it doesnt bubble. also add a shim behind the dropdown, this allows it to properly close even when used inside modals. sometimes modals will place their own shim that closes the modal and aborts the default mousedown event. in such cases the modal would close but the dropdown element would still float on the screen now detached and the only way to close it would be to make a selection
