Checks, whether a Focus change from oldFocus to newFocus implies a focus change to "toTest" or one of its child entries from some entry outside of "toTest". If newFocus is not toTest or one of its children "false" is returned. If the focus changes from one child of toTest to another or from a child of toTest to toTest itself or from toTest to one of its children, false is returned.
