QCoreApplication::removeNativeEventFilter does not use MainThread eventDispatcher

inconsistency between QCoreApplication:installNativeEventFilter and QCoreApplication:removeNativeEventFilter. 

InstallNativeEventFilter requests an instance of QAbstractEventDispatcher with: QAbstractEventDispatcher::instance(QCoreApplicationPrivate::theMainThread.loadAcquire());
RemoveNativeEventFilter requests the instance without MainThread parameter.
This results in a leak / filter is not removed, if the RemoveNativeEventFilter is called from a thread other than the MainThread.
