The OnPaneResize (and SizeChanged) event does NOT fire when a pane is unpinned. When it flies out from the left, resizing the flyout does not fire events that would letus refresh the chart to fill the new size.

I am trying to change the orientation of the SplitPane after the DockManager has rendered but nothing changes. It seems like the parameter is not reactive.

A possible option for the time being is to dispose and reinitialize the DockManager when you want to change the SplitPane Orientation.
Here is a runnable sample: https://blazorrepl.telerik.com/QfYHboFl280vuIkL03.
