[Bug 25923] isTypeSupported should be asynchronous

https://www.w3.org/Bugs/Public/show_bug.cgi?id=25923

--- Comment #10 from Jerry Smith <jdsmith@microsoft.com> ---
I agree that IsTypeSupported() mirrors functionality for IsTypeSupported() in
MSE and canPlayType() for HTMLMediaElements.  Both of those seem well suited to
a simple call and synchronous response.  

I'm not clear why the API would be better for triggering UI to enable EME if it
was asynchronous.  Is the intent to hold the response until UI is presented and
resolved, and then allow IsTypeSupported() to return?
