esm.run fails to bundle pixi-filters but esm.sh works

[plurry]

Description

v5.x of pixi-filters works fine with esm.run, but v6.x throws "Failed to bundle using Rollup" and asks you to open an issue here. I had opened an issue with Pixi (pixijs/filters#451) at first, but I think it's a problem with jsDelivr because using esm.sh works fine.

The complicated bug report template didn't make me a bit more diligent and almost made me not bother reporting it at all.

Actually, it looks like even though pixi-filters on esm.sh bundles fine, it doesn't work when you try to use it.

And it turns out even the main Pixi module on both esm.run and esm.sh fail silently on pixi.js@8 even though pixi.js@7 is fine, so I'm back to blaming something in Pixi's ESM build config.

Actually Skypack works fine.
