[Bug]: Invalid transaction params Error after switching account and network (EIP-1559 mismatch) #37570
Description
Describe the bug
After switching from a non-EIP-1559 network to an EIP-1559 network inside a connected Dapp, MetaMask continues to use outdated transaction parameters and throws an error:
Invalid transaction params: params specify an EIP-1559 transaction but the current network does not support EIP-1559
The issue persists until the MetaMask extension icon is clicked (which seems to refresh the internal state).
Expected behavior
MetaMask should automatically update its internal transaction type and network context when switching between networks with/without EIP-1559 support, without requiring a manual refresh

Steps to reproduce
- Connect wallet A to a network B that does not support EIP-1559
- Perform an approve transaction, then revoke (cancel) it
- In MetaMask extension, switch account (select another account)
- Connect the new account to the Dapp
- In the Dapp, switch network to one that supports EIP-1559 (e.g. Gnosis or any other)
- Try to perform a new transaction (approve, send, etc.) The gasPrice / estimateFees value is passed into the transaction.

The error remains until you click on the MetaMask extension icon (which forces an internal refresh).
After that, transactions work as expected.
