An issue was found with some BIP32 implementation, causing incorrect keys with certain seeds (starting with zeroes), see
https://blog.polychainlabs.com/bitcoin,/bip32,/bip39,/kdf/2021/05/17/inconsistent-bip32-derivations.html
Trezor implementation is not affected.
Nonetheless the newly added test vector can be included as an extra test (BIP32 test vector #4).
Test vector 4 is being added to the BIP32 BIP here:
