If you have two series in a chart, one of them with a lot of points and only the other with labels, the axis labels aren't correctly drawn.
The series with a lot of points seems to be determining step to draw the labels, even if it has no labels.

In the project attached, the series have more points as you click the draw button, but less labels are drawn.

There was an axis labels speed optimization introduced in v2016.19 (concretely in the commit ea504caa).

There was an axis labels speed optimization introduced in v2016.19 (concretely in the commit ea504caa) that seems to be causing this.
