The sidebar used to speed up a transaction while it's pending or after it has failed currently allows editing the gas limit, but that new limit is ignored. This is especially problematic for transactions that failed due to a low gas limit, as the problem becomes impossible to fix by retrying. The gas limit specified by the user is now used in the speed up transaction. Fixes #8156 Fixes #7977 |

Transaction Controller
Transaction Controller is an aggregate of sub-controllers and trackers exposed to the MetaMask controller.
- txStateManager responsible for the state of a transaction and storing the transaction
- pendingTxTracker watching blocks for transactions to be include and emitting confirmed events
- txGasUtil gas calculations and safety buffering
- nonceTracker calculating nonces

txMeta's & txParams
A txMeta is the "meta" object it has all the random bits of info we need about a transaction on it. txParams are sacred every thing on txParams gets signed so it must be a valid key and be hex prefixed except for the network number. Extra stuff must go on the txMeta!
Here is a txMeta too look at:
txMeta = {
"id": 2828415030114568, // unique id for this txMeta used for look ups
