HTML5 : Loader ProgressEvent.PROGRESS not dispatched


loader.contentLoaderInfo.addEventListener(Event.COMPLETE, completeHandler);
loader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, progressHandler);

complete is dispatched, ProgressEvent.PROGRESS is not dispatched


Did anyone success in working with Loader ProgressEvent on HTML5 ?

There was an improvement in the last release that may help with progress on certain browsers:

I tried to load a png (5 Mo) on Windows but progress event is not dispatched on Chrome, Edge, Firefox.
Does URLLoader progress event work better ?

ProgressEvent.PROGRESS work with URLLoader, I use Loader.loadBytes() to display image.
