A fix that prevents event bubbling in AvaPlot when nested in ScrollViewer was previously introduced in #5223.
But now in case when you've got a Plot with UserInputProcessor.Disable() inside ScrollViewer, you can't scroll the page while the mouse is over the Plot. Therefore, I believe that this behavior should be configurable at the plot control level.
