The homepage is a React thing, and for React apps you have to remove the base href, while in Angular apps you have to change it to “./”
Capacitor is framework agnostic, and doesn’t know if you use React or Angular or something else, and can’t make assumptions.
Those are not Capacitor bugs, Capacitor just provides plugin APIs for your electron app, but you still need to know electron and the framework configurations docs needed to work in electron. And if you don’t know them, you should be able to search them on the framework doc websites, because as I said, they depend on the framework you use, not on Capacitor.
