Richfaces SuggestionBox as a combobox doesn't disappear

I am using Richfaces suggestionBox as a combobox. You can see this usage in the second example of livedemo: http://livedemo.exadel.com/richfaces-demo/richfaces/suggestionBox.jsf?c=suggestionBox

The problem is that if I double c开发者_JS百科lick on the arrow icon, the suggestion box will not disappear after that. In fact, we just need to repeatedly click on the icon, the issue will occurs.

Thanks!
