TW Transactions to self seem to timeout without an error

[aeyakovenko]

Problem

Users tend to transfer to self as test.

Proposed Solution

I don't see why transfer to self would fail.

        SystemInstruction::Transfer { lamports } => {
            let from = next_keyed_account(keyed_accounts_iter)?;
            let mut to_account = next_keyed_account(keyed_accounts_iter)?.try_account_ref_mut()?;
            transfer(from, &mut to_account, lamports)
        }

My guess the TW integration includes the same account twice in the TX. explorer should show the AccountInUse error code, the timeout is super annoying.
