WebAssembly examples crash

I wanted to give the examples a try, but none of them work on Firefox 146.0.1 on Linux.

Opening any example shows the text "Loading WebAssembly ...", then the text disappears, but I do not see anything new on the screen.

The debugger shows:

Uncaught RuntimeError: unreachable executed

Reproduce the failure from the kiss3d examples link in Firefox 146.0.1 on Linux, then inspect the debugger trace in demos/quad/pkg/example.js and example_bg.wasm, especially the wasm_bindgen closure path. Done means the examples load past "Loading WebAssembly ..." and render without the unreachable runtime error.
