Describe the bug

During testing for #161 I encountered a legacy transaction that failed signing with: Code 6a80 APDU_CODE_BAD_KEY_HANDLE

It seems that this only happens with specific calldata that might be known to the device.

This is the transaction:

alloy/crates/signer-ledger/src/signer.rs

Lines 331 to 349 in d024781

	async fn test_sign_tx_legacy() {
	// https://github.com/gakonst/ethers-rs/blob/90b87bd85be98caa8bb592b67f3f9acbc8a409cf/ethers-signers/src/ledger/app.rs#L321
	let mut tx = alloy_consensus::TxLegacy {
	nonce: 5,
	gas_price: 400e9 as u128,
	gas_limit: 1000000,
	to: alloy_consensus::TxKind::Call(address!("2ed7afa17473e17ac59908f088b4371d28585476")),
	// TODO: this fails for some reason with 6a80 APDU_CODE_BAD_KEY_HANDLE
	// approve uni v2 router 0xff
	// input: bytes!("095ea7b30000000000000000000000007a250d5630b4cf539739df2c5dacb4c659f2488dffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff"),
	input: bytes!("01020304"),
	value: U256::from(100e18 as u128),
	chain_id: Some(69420),
	};
	/*
	assert_eq!(tx.encoded_for_signing(), hex!("f87005855d21dba000830f4240942ed7afa17473e17ac59908f088b4371d2858547689056bc75e2d63100000b844095ea7b30000000000000000000000007a250d5630b4cf539739df2c5dacb4c659f2488dffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff"));
	*/
	test_sign_tx_generic(&mut tx).await;
	}

Ported from an ethers-rs test, which also failed with the same error.
