IInteractiveQuickInfoContent::KeepQuickInfoOpen Property

Determines whether the interactive Quick Info content wants to keep current Quick Info session open. Until this property is true, the IQuickInfoSession containing this content won't be dismissed even if mouse is moved somewhere else. This is useful in very rare scenarios when an interactive Quick Info content handles all input interaction, while needs to keep this IQuickInfoSession open (the only known example so far is LightBulb in its expanded state hosted in Quick Info).
