🐛 Bug Report — Runtime APIs - missing Symbol.toStringTag everywhere

[panva]

All web api interface i've tried to get the Symbol.toStringTag give undefined, instead of their expected value.

For instance:

console.log('Response' == Response.prototype[Symbol.toStringTag])
console.log('Request' == Request.prototype[Symbol.toStringTag])
console.log('Headers' == Headers.prototype[Symbol.toStringTag])
console.log('URLSearchParams' == URLSearchParams.prototype[Symbol.toStringTag])
console.log('CryptoKey' == CryptoKey.prototype[Symbol.toStringTag])

logs all false where all true is expected

I can't check all prototypes for you but since the few i've tried all fail this setup it seems to be a global issue with these classes.
