When is the LostFocus event actually fired?

In the documentation it reads "Occurs when the control loses focus". As far as I understand e.g. a TabPage's LostFocus event should fire when focus leaves the page, e.g. by putting focus at anoter page or outside the TabControl. I suppose I may explicitly assign focus at a control by clicking on it with the mouse (under the assumption it's enabled and so on), but the TabPage's LostFocus event doesn't fire in this case?

Shouldn't the TabPage LostFocus fire in such a case or do I miss something?
Best regards,
