// If the store of a pad treeview is modified while the pad is unrealized (autohidden), the treeview
// doesn't update its internal vertical offset. This can lead to items becoming offset outside the
// visible area and therefore becoming unreachable. The only way to force the treeview to recalculate
// this offset is by setting the Vadjustment.Value, but it ignores values the same as the current value.
// Therefore we simply set it to something slightly different then back again.
