 The policies above already restrict these applications to loading as the top-level document. However, malicious third-party content can create a confusing and potentially exploitable user experience by navigating to one of the application’s documents in an unexpected way (e.g. navigating directly to an internal settings page). Such sequence breaking attacks are prevented by disallowing cross-origin navigations to the application. The application may only be launched by navigating to its [start\_url](https://developer.mozilla.org/en-US/docs/Web/Manifest/start_url) or similar well-defined entry point such as a [protocol handler](https://github.com/MicrosoftEdge/MSEdgeExplainers/blob/main/URLProtocolHandler/explainer.md) or [Share Target](https://github.com/w3c/web-share-target/). [Launch handling](https://github.com/WICG/sw-launch/blob/main/launch_handler.md) may also provide a safe method to allow more dynamic control over incoming navigations.
 
-Implementations may choose to make an IWA behave more “app-like” by only allowing them to be launched in a standalone window and assigning them a separate [storage shed](https://storage.spec.whatwg.org/#storage-shed) so that third-party storage from the user’s normal browsing session is not available. Proposed changes to the web platform in general to reduce access to third-party storage could eventually make the latter the default behavior for any origin.
