Bug_title

DynamicEIP1559GasProvider produced JsonRpcError: max priority fee per gas higher than max fee per gas

Steps To Reproduce

it only happened once, depends on the network

Expected behavior

gas fee calculation like it does all the time. The dynamic gas provider is pretty good, it only happened like twice

Actual behavior

Exception in thread "main" org.web3j.protocol.exceptions.TransactionException: JsonRpcError thrown with code -32000. Message: max priority fee per gas higher than max fee per gas

Environment

Web3j version, core 4.13.0
Java 17
Operating System: Windows 11

additional info, used gas provider constructor:

public DynamicEIP1559GasProvider(Web3j web3j, long chainId) {
    this(web3j, chainId, Priority.NORMAL);
}

so no priority or customMultiplier explicitly specified

Hi @Julius278 , I tried to reproduce this issue last week but I didn't success. I tried to use the gas provider as you mentioned

DynamicEIP1559GasProvider gasProvider =
                new DynamicEIP1559GasProvider(web3j, chainId, DynamicEIP1559GasProvider.Priority.NORMAL);

on sepolia using infura, but I didn't get this error even doing it multiple times. Do you have some more information so I can try again to reproduce the issue?
