Co-signatory of a (2 of 3) multisig account cannot sign an aggregate bonded tx (for creating a multi-level multisig)

[fajarvm]

There is a possible issue in Symbol Desktop Wallet where a multisig enabled account cannot sign an aggregate bonded transaction to become a cosignatory of a multi-level multisig account. Now, I'm not sure if this is an issue in the core code or in the desktop client.

Background:
I'm trying to setup a harvesting node on AllNodes, and as part of the process, I have to sign an aggregate bonded transaction created by an account managed by AllNodes. According to the instruction of AllNodes, I should be able to sign this transaction in Symbol Desktop Client by:

1. Go to Home,
2. Click on the aggregate bonded transaction, a transaction details pop-up dialog will be shown,
3. In the transaction details pop-up dialog, click on the confirm button

The problem:
There's no "confirm" button. (See screenshot)
This transaction details is also shown for all of my cosignatory accounts; no confirmation button.

Expected behaviour:

• There should be a confirmation button as seen here: https://docs.symbolplatform.com/guides/aggregate/signing-announced-aggregate-bonded-transactions.html
• A (cosignatory of a) multisig account should be able to sign an aggregate bonded transaction.

If more information is needed, I'd be happy to share.

@bassemmagdy I still can reproduce it. I am taking one multisig account with 2co-signers (ch1, chm2), convert chm2 co-signer into multisig with 2 co-signors (ch3, ch4). Initiating transaction from ch1 and expect to receive aggregate transaction in ch3 and ch4, but unsuccessfully.
