Split Button is missing Loading property

The Split Button component states in the docs that it has a loading property (same as all other buttons) but it is not exposed in the UI:
Would be nice if this was exposed in the UI.

Great point @Lewenhaupt! We're actually currently doing an audit of the loading states for all of our components, and will be adding a loading property to many more soon!

Apologies for the inconsistencies here, but I'm pleased to share that loading states will be greatly improved in the coming weeks.
