The 'input' event is fired when moving the slider with the mouse, but it's not when using the keyboard. The 'change' event is properly sent in both cases.

It can be tested here http://jsfiddle.net/ltilve/T8767/

The behaviour should be the same with independence of the device, dispatching the 'input' event in both cases.

Is the same issue reported at https://crbug.com/345611

DispatchInputAndChangeEvent can be inlined directly into the setValueAsDecimal() call.
