Errors with window.fetch when using CapacitorHttp enabled

[bsalesc]

We're using urql(https://github.com/FormidableLabs/urql) offline support which expects to get from fetch the error failed to fetch in order to identify that the will be on offline mode. Now that capacitor is replacing the browser fetch when android try to fetch without internet will return ConnectException or UnknownHostException, which is different than what they expect https://github.com/urql-graphql/urql/blob/59f43ca674b04b8ddd0b3823d605e4b23ec67bff/exchanges/graphcache/src/offlineExchange.ts#L116.

Wondering if capacitor should mimic what fetch on browser does as it replaces? Or should urql be responsible to catch all possible errors?
