When I updated our project to Vaadin 7.6.8 I realised that scrolling on a ComboBox no longer flips the result list but it moves the selection. It used to work with 7.6.7 and older versions. I found this issue in the latest release notes: https://dev.vaadin.com/ticket/19704 . Did this bugfix caused this bug? Or it is a feature and ComboBox will work in this way in the future Vaadin versions?
