I tried again, but the progress event was indeed not executed!
Even simulated downloads cannot be executed
Loader progress does not execute URLLoader progress execution
When targeting html5, Loader uses the JavaScript type HTMLImageElement to load images. On other targets, it uses an internal URLLoader to load the binary data and convert it into a bitmap after loading. I’m not sure why it was chosen to be implemented differently in html5, but that seems to be why it is not dispatching ProgressEvent.PROGRESS.
Based on some quick research, it appears that HTMLImageElement does not dispatch its own “progress” event. With that in mind, there is nothing for OpenFL to listen for, and that’s why it is not dispatching ProgressEvent.PROGRESS.

So how did everyone do it? Should I use URLLoader to load it?
