+The `transactionQueue` decorator internally keeps an updated reference for the recommended `baseFeePerGas` and `maxPriorityFeePerGas` from the connected chain to avoid having to fetch it right before sending a transaction.
+However, due to the way the fee values were overridden, it wasn't possible for users to explicitly pass in custom fee values.
+Now explicitly provided fee values have precedence over the internally estimated fee values.
