The existing method with the same name is wrapped here for a particular purpose,
so let's make it clear from the name here.  May be
|ProcessPendingPointerCaptureForPointerLock|?

Also, as Navid suggested, drop the |coalesced_events| parameter and create an
empty vector when calling |Create()| here.
