[Bug]: Metamask is using currently selected wallet nonce instead of "connected wallet" nonce

[dievardump]

Describe the bug

On Firefox, Let's say I connected account 0x1 to website1.com and I'm doing stuff with it.

I go to website2.com, and want to connect another account. I select account 0x2 in Metamask and then connect to that website2.

If I go back to website1, it is still 0x1 that is connected to the website. However, when I try to do a transaction, Metamask is using 0x2 nonce (and other details) in the window of transaction (but still submitting with 0x1 account)
This results in failed transactions since 0x1 and 0x2 have different nonces.

Expected behavior

Metamask should use 0x1 data to do the tansaction

Screenshots/Recordings

0x0399 has a nonce of 6938 but Metamask tried to submit with nonce 22 because current selected account in Metamask is at nonce 21

Steps to reproduce

1. Go to a website(1) and connect account 0x1
2. do a transaction
3. Go to another website(2), select account 0x2, connect, do some actions
4. Go back to website(1) and try to do a transaction, the nonce used will be 0x2 nonce since it's the selected wallet in Metamask (although not the connected wallet)
