In the documentation for the Kendo jQuery ToolBar, there is support listed for button group 'items.buttons.toggle' if the button is of type button and has 'togglable' set to true. However, it seems that if that button group is set to "overflow: 'always'" the toggle method stops functioning, even if the button is listed as togglable.
I've recreated the issue in this dojo:
Is the toggle method unsupported for overflow buttons? If so, I can't find any reference to that in the documentation.
