When a single user interaction with an input device generates a series of different input events, the
sourceCapabilities property for all of them will point to the same instance of
InputDeviceCapabilities. For example, when a user lifts their finger off of a touchscreen, several UIEvents may be generated including
focus. All of these events must have the same
sourceCapabilities representing the touchscreen.
A device is considered "responsible" for an event only when that interaction is part of the abstraction provided by the web platform. For example, many user agents allow a window to be resized with a mouse or a keyboard, but this detail is not exposed to the web platform in any way, and so the sourceCapabilities of a resize event will typically be null.
