I'm trying to use a checbox in the context of MenuItem, but the indeterminate state is not rendered. Is there a particular reason for this? It feels rather strange as a user to see it like that.
For a situation in our application, we need to be able to toggle a three-state checkbox between on and off, but display the indeterminate state. Would it be possible to introduce a Mode property to allow for this? If clicked when indeterminate, toggle to false. False to true. I have already implemented my own version of this, but it would help if we could get it out of the box.
