BrowserProvider network change event is not fired

network event listening

Describe the Problem

Well, I'm just subscribing to provider network change event (using .on('network')) and nothing is emitting when I change network in my Metamask wallet interface. When subscribing via window.ethereum.on('chainChanged', () => {}) and switching network, the callback is executed.

I'm using hardhat localhost network and Sepolia test network with deployed contract, but as I see, the issue is in provider itself.

Please, help me to understand the issue and resolve it.

Repo with source code (App.tsx, initWeb3 function) - https://github.com/kubarenatioN/dElection/commit/e1efb2c8c4e6bda8e4df2099e7ede2cb8385aca2#diff-e56cb91573ddb6a97ecd071925fe26504bb5a65f921dc64c63e534162950e1ebR53

Code Snippet

// Provider initialization
provider = new ethers.BrowserProvider(window.ethereum as any, 'any');

// Later in code when subscribe to events
// This just ignores network change.
      provider.provider.on('network', (...args) => {
        console.log(123, args);
      });

      // This will work and log in console.
      (window.ethereum as any).on('chainChanged', (...args: any[]) => {
        console.log(222, args);
      })

Moreover, similar issue have already happened to another dev. He asked about it here, but get no response - https://github.com/ethers-io/ethers.js/issues/2842#issuecomment-1126837212

Also, I found this issue - https://github.com/ethers-io/ethers.js/issues/1396 There we have some explanation on usage of .on('network', () => {}), but still, my original question is about that it doesn't work as intended, or I'm missing some details...

Waiting for some help. By the way, thanks for your great work!
