Trigger event keyDown on Contenteditable element (testing + react + jest + enzyme)

I am using enzyme + jest to test react App, is it possible to trigger onKeyDown event on contetnteditable span element?

Editable text

I tried:

result.find('#name').simulate('keyDown', { key: 'm', keyCode: 77, which: 77 });,

but it did not work. Element content stayed unchanged.
