Add "supported" getter to experimental features like MediaSource to check availability #19720

This issue was originally filed by robert.w.ha...@gmail.com

I was "hacking down some dart code" to create an example for using MediaSource for HTML5 Video. When trying it in different browsers I got an exception that MediaSource is not available (UnknownJavaScriptObject)

I did some research and didnt found a way to check if MediaSource is available or not or is there a way?

I'd like to see anew feature in dart, that allowes me to check if MediaSource is available. E.g. MediaSource.supported like there is for https://api.dartlang.org/apidocs/channels/stable/dartdoc-viewer/dart-dom-html.EmailInputElement#id_supported

Regards and Thanks for feedback, Robert

Not really a new feature, just a matter of adding the right bit to the right python script to generate it for this class as well. And availability for this feature is amazing. In Firefox, only if you set a flag, and even then defaults to working only if your domain is YouTube.
