WebGL example seems broken

[mousetail]

Describe the Bug

The page of the webGL example seems blank. It shows the following error for me on Firefox 99: (Majaro Linux)

TypeError: _index_bg_wasm__WEBPACK_IMPORTED_MODULE_0__.memory is undefined

If I try to run locally I get the following error:

Same here in Firefox 100 on Fedora

It doesn't work in Chrome either, but the error is different:

TypeError: Cannot read properties of undefined (reading 'buffer')

    at __webpack_require__.a (index.js:119:13)

I think this could be an issue with the webpack plugin. I'm currently running my own project, not related to WebGL but I'm building using @wasm-tool/wasm-pack-plugin. When I try to run my code in the browser, I get the same error as @jacopofar :

    at eval (index_bg.js:627:30)

I think that's caused by #2961, so it should be fixed with the git version of wasm-bindgen.
