As pointed out by @acolwell, original CORB implementation was done before OOR-CORS and therefore had to cover both `no-cors` and CORS.  Once CORB (as spec-ed!) covers only `no-cors` requests, then possibly `application/dash+xml` shouldn't mater at all, because 1) Chrome/desktop doesn't have native support for DASH in video.src and 2) other implementations (e.g. Chrome/Android or Safari) only allow same-origin DASH.

Based on the above, we should just mark the current bug as closed.  (Possibly following up separately on universally requiring CORS for DASH/HLS/etc).

PS. From ORB side this was discussed in https://github.com/annevk/orb/pull/23#issuecomment-790905834 and in https://github.com/annevk/orb/issues/20
