[Bug]: Passed transaction nonce is ignored

[compojoom]

Describe the bug

At the safe wallet, we are building a speed up TX function: safe-global/safe-wallet-web#3425
We are polling the RPC for the submitted TX and if we don't find it withing X seconds we offer the option to speed that transaction up. A transaction that needs to be sped up consist of mainly of {to, data, nonce} fields. Nonce is extremely important as it has to be the same as the TX that has been already submitted.
to speed up the transaction we call:
result = await signer.sendTransaction({ to, data, ...txOptions })

This works fine with the Metamask Browser Extension, but is buggy when used with Metamask Mobile.
Metamask mobile appears to ignore the provided nonce and just increase the nonce. I've looked around the MM-Mobile code and found where the problem comes from.
There are 2 cases.

Case 1:
The user has not enabled "customize transaction nonce" in the settings.
So here despite the fact that we've passed a nonce, the transaction.nonce is being reset to undefined:

metamask-mobile/app/components/Views/confirmations/Approval/index.js

Line 412 in 0e2c734

transaction.nonce = undefined;

because showCustomNonce is not true.

Please note that the Browser extension actually works fine. If we send a nonce there, it is set as the nonce of the tx that the user is executing. From our perspective the MM-Mobile behaviour is not expected

Case 2:
"customize transaction nonce" is set to true. If this option is on, the TransactionReview component renders the TransactionReviewInformation component. On DidMount this component sets the TX nonce to the next network nonce:

metamask-mobile/app/components/Views/confirmations/components/TransactionReview/TransactionReviewInformation/index.js

Line 251 in 0e2c734

const { showCustomNonce } = this.props;

this now changes the provided transaction nonce, so we effectively end up again ignoring the nonce that the Dapp has provided.

This behaviour is also diverging from the MM Browser extension, where the nonce provided by the dapp is treated as the nonce for the "custom nonce" component.

We think that this behaviour is wrong and MM Mobile should behave as the MM Browser extension

Expected behavior

Provided dapp nonce should be used for submitting the TX.

Steps to reproduce

1. Go to: https://feat_pending_txs--walletweb.review-wallet-web.5afe.dev/home?safe=eth:0xA77DE01e157f9f57C7c4A326eeE9C4874D0598b6
2. Connect your MM Account
3. Switch to sepolia and deploy a test safe (you can use the sponsored tx)
4. Now try to submit a Transaction
5. Wait for 15 sec you should see a speed up button
   
6. Click the button and speed up the TX
   
   Note the wallet nonce
7. Notice that on the Review screen in MM the nonce is different:
