InvalidAccessError: key is not extractable

[jaxoncreed]

When running generateKey with extractable set to false:

await generateKey({"name": "ECDSA", "namedCurve": "P-256"}, false, ["sign", "verify"])

the following error is always thrown:

stringify error InvalidAccessError: key is not extractable

This was encountered by others too: smallbets/userbase#275

The above code should generate a key pair with an unextractable private key.

That's simply impossible. As the library is a bridge between native space and the browser. if a key is not extractable it simply cannot be communicated back to the native space from the browser.
