Severity

serious, but I can work around it

Additional Information

I have import a large wasm file (size 1.6M) in sw.js, if inline the wasm file will make sw.js load slow. (assetsInlineLimit: 0 option is not working for sw.js)
My current solution is to copy the wasm files to the static directory and manually set the wasmUrl
