OptionContainer doesn't re-open after lost focus

[uriuriuriuriuri]

First of all, thanks for the investment and code maintenance, not trivial and highly appreciated!

My problem is when I open the optionContainer and then scroll down the page using the scroll bar (of the page), the optionContainer of course closes because it has lost focus, but when I click again in the search box it does not open only if I click on some point outside it and then once again inside it.

And once again thank you for all the effort.
