One more thing:

When changing network but rejecting to change in MM, the application remains in the newly chosen network and allows to send tx. Which results in unexpected behavior for gas estimation/contract interaction etc.

To Reproduce
0. Go to https://mstable.app/

1. Connect Wallet
2. Set to Polygon and accept change.
3. Change in the App to Ethereum
4. Reject the change from MM

The App remains in Polygon, while MM is in Ethereum.
