Dropdown: When clicking to close a dropdown, it fires "click" and "blur" events

This issue happens when controlling manually (via states) the status of a dropdown.

Steps

If you click the "Not ok button" to close the drop-down you will notice that it triggers the click and blur events (It shouldn't fire blur cause I'm still inside the component).

Now, if you click the "ok button" repeatedly, you will notice that only the click event is fired, regardless if the dropdown is opening or closing, and the blur happens only when you actually click outside of the related button, as expected.

Expected Result

When clicking the "not ok button" to close a drop-down, it should fire only a click event.

Actual Result

When clicking the "not ok button" to close a drop-down, it fires a click and blur event.
