Steps to reproduce the issue

1. create an inputWidget with the TreeInput-class and render the page.
2. select node in TreeInput
3. Dropdown closes only when clicking elswhere

Expected behavior and actual behavior

When I follow those steps, I see normal behavior asif 'autoCloseOnSelect' is false.
