Current behavior
I would like to set inline styles and style classes to the context menu items. When I try and set styles using the MenuItem model, they do not get rendered to the page.

Expected behavior
When style or styleClass are set on the MenuItem, those styles should be applied to the respective context menu item.

Minimal reproduction of the problem with instructions
See the Plunker example above. I would expect the menu item in the context menu to have the 'tallyho' class applied to it.

What is the motivation / use case for changing the behavior?

Custom styling for menu items is a great feature.

Same problem with the menubar, I modified the plunker to use the class on another element.
