HTML5 video does not open in Chrome

[pro2s]

HTML5 video does not open in Chrome, because Chrome ignores the async: false parameter in the ajax request in the _getRemoteContentType method. _getRemoteContentType returns undefined as contentType, so _showHtml5Media generates error 'Could not detect remote target type. Force the type using data-type'.
