I have a link to a video (see first screenshot) in a modal (see second screenshot) which works great when the user clicks the video link, which blurs and darkens the background behind the video modal. However, if the video is watched (note that you won't be able to close out the modal until 30 seconds after the modal launches) and the modal is closed.
However, if the user clicks on that link again, the modal appears and shows the background blur and darkening, but the video doesn't show like the first time, so users can't click out of the modal.
