I think the correct fix for this is to add a `qaUserPrioritySpeaker->setEnabled(false);` to the `if (cu) {` block in `updateMenuPermissions()`:

	if (cu) {
		// [...]
	} else {
		qaUserMute->setEnabled(false);
		qaUserDeaf->setEnabled(false);
		// qaUserPrioritySpeaker->setEnabled(false);   <--- insert here
		qaUserTextMessage->setEnabled(false);
		qaUserInformation->setEnabled(false);
	}
