… Lite) Sweeping for repeats of the WPF Popup wedge bug found CorrelatedCrosshairManager has the same shape as ChartHoverHelper — multiple charts feed a single tooltip popup, IsOpen = true is set on every mouse move with no re-anchor toggle, and no Loaded/Unloaded/IsVisibleChanged subscriptions on the chart lanes. CorrelatedTimelineLanesControl is hosted inside Resource Metrics → Server Trends (a TabItem inside a TabItem), so the same wedge applies: WPF unloads the parent on tab switch without firing MouseLeave, leaving _tooltip.IsOpen stuck at true with a stale anchor. Both Dashboard and Lite copies updated in lockstep per the file's own SYNC WARNING: - Subscribe to chart Loaded / Unloaded / IsVisibleChanged in AddLane and force _tooltip.IsOpen = false on each event. - In OnMouseMove, toggle IsOpen off then on so WPF re-evaluates placement even when the popup believes it is already open. - Unhook the new event handlers in Dispose.
