mfoltzgoogle has just created a new issue for https://github.com/w3c/presentation-api: == Receiving browsing context needs additional flags set == The receiving browsing context sets the _sandboxed auxiliary navigation browsing context flag_ to prevent it from using e.g. window.open() to spawn new browsing contexts. However we should also prevent top-level navigation (to protect integrity of the screen selection prompt) by setting the _sandboxed top-level navigation browsing context flag_. This also blocks `window.close()`, thus developers will have to call .terminate() for a presentation to close itself. We can also set the _sandboxed modals flag_ to prevent modal dialogs, which is suggested in a non-normative note, but not enforced. I don't feel as strongly about this however.
