Can not interact with markers on multi-area plots

[Veneti]

Summary: On multiplot charts when chart type is Areas and plot line for first plot crosses plot line of second plot some of the plot markers are not receiving events. Observable with renderer is SVG, not tested with other renderers. The issue is that area of second plot is covering markers of first plot thus markers do not receive events, the overlaying area is.

Expected: All markers receive events (thus can be magnified, display tooltips etc.) regardless of if/how plots cross. Example: ​http://www.highcharts.com/demo/area-basic

Chart renderer: SVG

Code:

    var theme = new dojox.charting.SimpleTheme({
	plotarea: {
    	fill: "rgb(0,0,0,0)"
    },
    marker: {
        stroke:  {width: 2, color: "#fff"},
        outline: {width: 2, color: "#fff"},
        font: "normal normal normal 8pt Verdana, Arial, sans-serif",
        fontColor: "#999999"
    },
    markerThemes: [
        {fill: "#fff", stroke: {color: "#3399cc"}},
        {fill: "#fff", stroke: {color: "#009900"}}
    ],
    axis: {
        tick: {
            color: "#fff",
            font: "normal 14px Arial",
            fontColor: "#999999"
        },

            color: "#c9c9c9",
            style: "LongDash"
        }
    }
});


var xData1 = [10, 15, 5, 10];
var xData2 = [10, 5, 15, 10];
var xLabels = [ "a" , "b", "c", "d"];
var chart = new dojox.charting.Chart("openbugsday", {
    fill: "rgb(0,0,0,0)"
}).setTheme(theme)
  .addPlot("sales", {
    type: "Areas",
    markers: true,

This is unfortunately by design. Changing this is a valid request however I'm just changing it to enhancement request.

Given that no one has shown interest in creating a patch in the past 2+ years, I'm closing this as patchwelcome.
