CategoryAxis.justified=true not applied with RangeArea with style="step"

[kendo-bot]

Public item: https://feedback.telerik.com/kendo-jquery-ui/1636648-categoryaxis-justified-true-not-applied-with-rangearea-with-style-step
I need that the point will be in the start of chart (like justified property behavior) and the line style of "rangeArea" type property will be "step".

In this example the point in the start and the justified property works as expected.

but in the second example, when I added property: line: {style: "step"} to "rangeArea" type, the point start in the middle of labels, and justified property not working.

So I need that my chart will be like the second example, but the start point of the line will be like the first example.
