The ServiceWorker assigns an app-version to a each client to ensure that all subsequent requests for a client are served using the same app-version. The assignment is done based on the client ID. Previously, the ServiceWorker would only try to read the client's ID off of the `FetchEvent`'s `clientId` property. However, for navigation requests the new client's ID will be set on [resultingClientId][1], while `clientId` will either be empty or hold the ID of the client where the request initiated from. See also related discussions in w3c/ServiceWorker#870 and w3c/ServiceWorker#1266. In theory, this could lead to the navigation request (i.e. `index.html`) being served from a different app-version than the subsequent sub-resource requests (i.e. assets). In practice, the likelihood of this happening is probably very low though, since it would require the latest app-version to be updated between the initial navigation request and the first sub-resource request, which should happen very shortly after the navigation request. This commit ensures that the correct client ID is determined even for navigation requests by also taking the `resultingClientId` property into account.
