WinForms had been changed to pin the first active download to the top on every
start, which interrupts anyone who has scrolled further down the queue - the
behaviour master's comment says it deliberately avoids. Avalonia kept master's
gentler version but never read the setting, so Chardonnay's checkbox did nothing.
Both now run master's logic - scroll the new item into view only when the
previous one is visible - gated by AutoScrollQueue. VirtualFlowControl.ScrollToTop
had no callers left, so it goes.
