* Allow submission of transactions with dapp suggested gas fees, while estimates are loading * Allow editing of transactions with dapp suggested feeds, while estimates are still loading * Ensure that advanced gas is always editible inline when gas is loading * Ensure that insufficient balance error is shown when gas is loading if the user has customized the gas * Only set gas price insufficient errors if the current network is non-eip-1559, or the txparams actually have a gas price * Remove unnecessary param * lint fix * ensure insufficient balance warning is showing when loading * Ensure that eip1559 network transactions do not combined eip1559 and non-eip1559 gas fee properties * Lint fix
