absolute-position of an element nested in a Flickable double-counts the
element's own layout offset (measured: abs.y = true_y + root.y), so the
collapsed-sidebar folder flyout drifted down by one row-pitch per row
(lower folders left the viewport) and the track drag ghost plus the
playlist drop-target hit box drifted the same way. Subtract root.{x,y}
to recover the true window position; scroll-safe because root.{x,y} is
the row's fixed in-layout offset, not the viewport scroll. Rows outside
a Flickable (the section nav rows) are unaffected and left as-is.
Sites: SidebarRow folder-flyout anchor + recompute-drop hit box;
TrackRow drag down/threshold/start/move coordinates.
