How to reproduce :

- Create a dropdown button with some items

- Open it with your mouse

What happens :

The first button is automatically focussed. Even with mouse use.

Feature request :

Allow to focus on nothing if you use the mouse.

Or allow to select the default focussed item with an input of DropdownButton component. It could accepts no default focus.

In the moment the kendo-toobar-dropdownbutton look like an "normal" toolbar-button. The user has no visual indication that the button reveals a drop down list.

Please add a dropdown-arrow like it is present in the split-button to the dropdown-button.
