SP5: HorizontalLine and VerticalLine labels styling #3056
Description
First, Label should have an IsVisible property which is set to false when new axis lines are created
Next, weird things are happening where the line's label isn't being styled as expected
var hl = plot.Add.HorizontalLine(0, 1, Colors.Black, LinePattern.Dash);
hl.Label.BackgroundColor = Colors.Transparent;
hl.Label.Border.Color = Colors.Transparent;
hl.Label.Text = "OOF";
hl.Label.Font.Color = Colors.Green;
