Expected behavior

Game should load and work.

Error dispatching event EventObject(EventObject { type: "addedToStage", class: flash.events::Event, ptr: 0x3dd3a78 }) to handler FunctionObject(FunctionObject { ptr: 0x3dd3628, name: Ok("ib2/init()") }) : RustError("Error: Invalid object"

This is due to trying to read an object which uses "external decoding" or flash.utils.IExternalizable specifically an Object requires parsing via "UI.ibScriptDataNode". Currently flash-lso can only handle pre-registered decoders for specific classes and can't handle calling back into Ruffle, easiest way is probably to support a 'fallback' decoder but that's still going to need some work.

Seems to have regressed, play prototype button isn't loading

The error is Error loading ABC file: VerifyError: Error #1103: Class stdpx.filters::EdgeDetectionFilter cannot extend final base class.. This is happening because the SWF tries to extend the ConvolutionFilter class, which is incorrectly marked as final in Ruffle.

Button regression has been fixed, swf still gets stuck on gray screen when pressing play
