`InputDispatcher` tracks two pieces of state information regarding Pointer Capture:
-- `mFocusedWindowRequestedPointerCapture`: Whether or not the focused window has requested Pointer Capture. This is updated whenever the Dispatcher receives requests from `InputManagerService`.
+- `mCurrentPointerCaptureRequest`: The sequence number of the current Pointer Capture request. This request is enabled iff the focused window has requested Pointer Capture. This is updated whenever the Dispatcher receives requests from `InputManagerService`.
- `mWindowTokenWithPointerCapture`: The Binder token of the `InputWindow` that currently has Pointer Capture. This is only updated during the dispatch cycle. If it is not `nullptr`, it signifies that the window was notified that it has Pointer Capture.
