what if confirmed transaction did not match intent but staking operation is valid, then we won't catch the error?

This code is used for check:construction only, we never full tested staking txns in check:construction.
Staking operation looks like this:
"network_identifier": {
"blockchain": "abc",
"network": "testnet"
},
"operations": [
{
"operation_identifier": {
"index": 0
},
"type": "stake",
"status": "",
"account": {
"address": "dydx12c0xh69avh8xd0z76as9as4mcy0cfncukmmd7z",
"metadata": {}
},
"amount": {
"value": "5000000",
"currency": {
"symbol": "COSMOSDYDX",
"decimals": 18
}
}
}
],
"suggested_fee_multiplier": 2,
"metadata": {
"gas_adjustment": 0.5,
"validator_src_address": "dydxvaloper10lzv79d96l7jh07z76ry6cnn6ftnnl8fgketzu",
"validator_dst_address": ""
}
}
The amount in the preprocess API is a positive number, but our block API interprets staking as two operations; the first one is negative. Hence we get an intent mismatch.
