when signTransaction is given a transaction object, it mutates the object by removing from field

Code Snippet

const test = async () => {
	const wallet = new ethers.Wallet('0x0000000000000000000000000000000000000000000000000000000000000001', new JsonRpcProvider('https://holesky.drpc.org'))
	const tx = { from: '0x7E5F4552091A69125d5DfCb7b8C2659029395Bdf' }
	await wallet.populateTransaction(tx)
	console.log(tx.from)
	await wallet.signTransaction(tx)
	console.log(tx.from)
}
test()

this prints:

0x7E5F4552091A69125d5DfCb7b8C2659029395Bdf
undefined

It should print:

0x7E5F4552091A69125d5DfCb7b8C2659029395Bdf
0x7E5F4552091A69125d5DfCb7b8C2659029395Bdf
