MM disconnection on page reload

[agualis]

AKA Cannot read properties of undefined (reading 'listenerCount')

Sometimes the Metamask connection is disconnected when reloading certain pages.

This is probably a Metamask related bug but it is quite frequent:
https://balancer-labs.sentry.io/issues/5735188657/

Steps to reproduce:

1. Go to balancer.fi or to a preview url

• it does not happen in dev or when locally building and serving a build so it could be SSR related

2. Connect with MM
3. Go to swap page
4. Manually change url params (for instance from /swap/ethereum to /swap/base/USDC) and refresh the page
5. Repeat 3 until you get the disconnection
6. you should see a Cannot read properties of undefined (reading 'listenerCount') error in the console

Note: It is not a problem in the swap page as I could also reproduce it by reloading the pool detail page with different pool ids
