thanks for your hints, I've downloaded the Q2 2014 beta version, functionally, it works as expected. But, the icon for "clear formatting" is not showing, I am not sure if this is a bug or am I missing something?
I am using the bootstrap integration with kendo ui ("Kendo UI Bootstrap"), like the sample shown here: http://demos.telerik.com/kendo-ui/bootstrap/
. Could you please check it out if this is really a bug?
