Semantic UI React – The input in dropdown does not allow space

I have a drop-down list of nested text input. After adding onClick={event => event.stopPropagation()} I can select and enter an input for the inputs. However, as soon as I hit the spacebar, the dropdown list closes.

I've worked out adding multiple or closeOnChange={false} for the dropdown, the dropdown remains open, but the onChange the input is not triggered, which means that the white space is not added to the string and effectively results in a noop.

I created a simple pen to illustrate the problem that can be found here.
