(In reply to comment #10)
> One of the difficulties of parallel image decoding is it is not always safe to call the observers in main thread, because that can trigger JS execution.
> 
> Please take a look at PageGroupLoadDeferrer and relevant code. For example, when a JS modal dialog is being showed, no JS event is supposed to be dispatched.
> 
> The other side of this problem is that one image source can have different observers from different pages, so it cannot get a pointer to a page. One solution may be making the load defer state globally accessible.

Thanks for the comment. We will investigate this issue!
