Setting minPointLength on a reversed x-axis xrange-chart will squish all ranges to minPointLength

[satub]

Expected behaviour

When setting minPointLength to 1, xranges with 0 length should show up as if a vertical line, while wider xranges should render normally.

Actual behaviour

When x-axis is reversed, all ranges are squished into lines with width of 1, regardless of their width.
