D28936: Use a Proxy object to detect changes within the MediaMetadata

[Fabian Vogt]

fvogt added a comment.


  AFAICT (take with a grain of salt, I'm a JS n00b) this doesn't catch 
something like this:
  
    let a = {};
    navigator.mediaSession.metadata = a;
    a["foo"] = "bar";
  
  And behaves weirdly if you do:
  
    let a = navigator.mediaSession.metadata;
    navigator.mediaSession.metadata = null;
    a["foo"] = "bar";

That appears to work fine here
