File Browser Won’t Open in s2online.github.io

[FlamedDogo99]

Describe the bug

s2online.github.io contains a copy of the original scratchflash editor and player. Loading the website with ruffle causes no errors, however many features are broken, such as uploading a file or moving blocks in the editor.
Here is the swf file: https://github.com/FlamedDogo99/FlamedDogo99.github.io/blob/main/Scratch.swf

Additional information

I’m assuming this is just due to AMV2 features that haven’t been implemented yet, but I thought it wouldn’t hurt to report this.

Continuing from #9058 (original Scratch 2 issue). A list of issues:

• XML.setName (avm2: Implement XML.setName #12979) unimplemented, causing issues with drawing sprites
• Unimplemented XML features preventing adding text to sprites (RustError("Modifying an XMLList object is not yet implemented: target XmlObject(XmlObject { ptr: ... })")) (fixed by avm2: Improve XMLList set_local_property #13255)
• In Scratch 2, cannot drag blocks #13108 preventing dropping blocks (fixed by avm2: Implement DisplayObjectContainer.getObjectsUnderPoint #11970)
• FileReference.browse unimplemented in AVM2, causing the file browsing issue
• TextField.restrict (avm1,avm2: Implement TextField.restrict #14634) unimplemented allowing for adding letters and other characters inside a number-only block

Shoot didn't realize this was a duplicate, thanks!

[Lord-McSweeney]

Currently this mostly works but starts up slowly due to by.blooddy.crypto.image::PNG24Encoder.encode taking a long time to run.

Also downloading just doesn't work, although I don't know if that was being addressed with this originally

Everything appears to be functional now.
