List closing on scrollbar clicking

[cheluis]

I have a Autocomplete on a dialog-like, but then I click the scroll bar or when I try to drag it, the list closes. I was looking this link:https://prototype.lighthouseapp.com/projects/8887/tickets/114-autocomplete-div-scrollbar-closes-suggest-list and tried to implement that solution but nothing. I have an error that says event.srcElement.focus() not defined. Looks like the event object its not passed to the onBlur function.
