With ZoomMode=X, chart pans on click without dragging

[planetarian]

Currently I am partially working around this by setting MinLimit = -(items.Count()/16.0), MaxLimit = items.Count() on the X Axis. This doesn't actually fix anything, but it at least sets the limits to be roughly similar to the post-pan limits by default, so that the movement on click isn't as jarring.

The secondary issue is that ChartPointPointerDown executes before it can even be determined whether the user is dragging or clicking, and there is no ChartPointPressed or ChartPointPointerUp or ChartPointClicked.
For that, I'm making use of everything I have at my disposal: ChartPointPointerDown to get the ChartPoint, and MouseDown and MouseUp to determine whether we're clicking or dragging.

        object? mouseDownObject;
        Point? mouseDownPos;
        ChartPoint? chartPoint;

        private void CartesianChart_MouseDown(object sender, MouseButtonEventArgs e)
        {
            // Store the clicked object and mouse position for comparison on MouseUp
            mouseDownObject = sender;
            mouseDownPos = e.GetPosition(this);
        }

        private void CartesianChart_ChartPointPointerDown(IChartView chart, ChartPoint point)
        {
            // Store the clicked point for use on MouseUp
            chartPoint = point;
        }

        private void CartesianChart_MouseUp(object sender, MouseButtonEventArgs e)
        {
            if (DataContext is not MyViewModel vm)
                return;

            // Ensure we're still acting on the same object
            if (sender != mouseDownObject)
            {
                mouseDownObject = null;
                return;
            }

            // If the new position isn't the same as the old one, we're dragging, not clicking
            Point pos = e.GetPosition(this);
            if (pos != mouseDownPos)
                return;
            
            // Get the series and point model and execute the appropriate point activation function for that series
            var series = (ColumnSeries<(string Key, double Value)>)((CartesianChart)sender).Series.First();
            var pointModel = ((string Key, double Value))chartPoint.Context.DataSource;
            vm.ActivatePoint(series, pointModel);
        }
