Locked nodes with tooltip.

In our app we show tooltip for locked diagram node. But, when we update mindfusion from 3.9.5 to 4.1.9, tooltips is no longer appears when mouse enters locked diagram node. Is this behaviour correct in new version? If so, could you tell please how to make tooltip visible in this case? You can use attached project below.

Thank you for your help. I have additional question. When i subscribe on `MouseEnter` or `MouseLeave` in ShapeNode or SvgNode, these events does not invoke. Could you tell me please why this happens and how make these events work?

DiagramItem inherits from FrameworkElement for its Xaml styling support and properties, but won't raise its events. Not sure if our developers noticed them at all, as we maintain own event API across multiple platforms for consistency. In this case, try using Hovered / PointerEnter / PointerLeave events listed here instead:

If you prefer handling events of individual items, you might try overriding CreateRenderer method in custom classes and handling returned element's events instead. Or alternatively attach events to root element of node's custom Xaml template.
