[Bug] MsgConvertCoinToEvm Tx - Intended toEthAddr Not Final Receiver

[CalicoNino]

When triggering MsgConvertCoinToEvm, the intended toEthAddr does not end up being the final receiver.

Example:

const msgs: EncodeObject[] = [
  {
    // ERC20 0xcA0a9Fb5FBF692fa12fD13c0A900EC56Bb3f0a7b
    typeUrl: "/eth.evm.v1.MsgConvertCoinToEvm",
    value: MsgConvertCoinToEvm.fromPartial({
      toEthAddr: "0x59005464D636ECd97Da8F15adFD36B16808f66F0",
      sender: signerAddress, // Your wallet address
      bankCoin: { denom, amount: "1" },
    }),
  },
];


const tx = await txClient.signAndBroadcast(signerAddress, msgs, "auto");

console.log(tx);

// Parsing the tx, we see that the receiver of the token is
// 0x4631356164464433364231363830386636364630
// Can also confirm that 0x4631356164464433364231363830386636364630 received tokens instead of the intended receiver.

Initially, I thought it had something to do with encoding during the signing of the tx, but after testing, I can confirm that the correct address is being signed and broadcasted. You can check this by calling txClient.sign(...) and then decoding the signed raw tx bodyBytes. Also, when performing with Keplr, you can also decode the correct ETH address.
Next, I checked the ts Protos, which list toEthAddr as a string. Upon comparing it with the initial Protos, I noticed that it is listed as a custom type.

happy to take ideas but my thought was the issue with MsgConvertCoinToEvm had something to do with the proto custom type. Since it doesn't take it as string
