I can't speak to what that error is but Chrome 96 appears to be from Nov '21 at the earliest which would include a large number of these mitigations.

w.r.t. js vs web asm: I could be wrong but I think V8 is the engine involved with webassembly as well so I'm not sure the wa vs js distinction matters here, but even so my main point is that there were significant software mitigations put into place in the browser. I'd expect reproducing this attack today would be difficult.
