 * Returns the sign typed data parameters with the message reduced to the fields declared in

 *
 * Extra properties do not change the EIP-712 hash, but they are serialized into the
 * `eth_signTypedData_v4` request, so wallets display them and wallet security checks scan them:
 * Rabby warns that "the transaction is not associated with the website that initiated it" when a
 * URL anywhere in the payload does not match the connected site. Structs assembled by spreading
 * API objects (offers carrying nested NFT and collection data) must therefore be stripped before
 * reaching the wallet.
