What makes it require that WASM extension you need the flag for in Firefox? Was there really no way to work around it or polyfill it for it to work? It is performance critical?

It is required in order to yield the event loop and force an implicit sync on OffscreenCanvas. There is technically a slower workaround for this but JSPI is coming soon anyway to firefox 153 and safari 27.
