Certain web APIs ping the parent process to open a permission prompt for users. While some APIs e.g. `Notification.requestPermission()` is guarded behind transient user activation, other APIs e.g. `navigator.geolocation.watchPosition` is not, and calling such API repeatedly can stress the parent process enough that the whole Firefox UI hangs.
