In fairness, wouldn’t that have less to do with custom behavior and more to do with the limited size of a phone’s screen? As someone who builds a video-based site often used on mobile devices: I don’t think that really matters. Not all sites using HTML5 video elements are just wrapping a single video in a player and some supporting content, the way you see on sites like YouTube or Vimeo. There are numerous applications for video where that content is integrated with other content on the page and not the only star of the show. There are standards for how HTML elements are supposed to work, and work together. And Apple is completely ignoring those standards in this case, which makes it literally impossible to provide the kinds of presentation styles and UIs we should be able to for visitors using iPhones.
