When user collapsed QSPanel at non-first page, QuickQS always remained
View.Visible. When user canceled collapsing, QQS remained clickable
although invisible to user(alpha = 0).
QQS must be non-clickable when user cancels collapsing at non-first page.
Test: QSPanel > 2nd page > Cancel collapsing while collapse QSPanel
> Verify invisible QQS is non-clickable
