Data series (line) disappears at very large zoom-in factor (have fix)

[pantopela]

Steps to reproduce

1. Create a line plot
2. Zoom (a lot) in

Platform:
.NET version: 4.8 / 6

Expected behaviour

Line in plot should still be visible

Actual behaviour

Line in plot disappears

Known fix/workaround

In CanvasRenderContext.DrawLine():

replace
streamGeometryContext.BeginFigure(firstPoint, false, false);
with
streamGeometryContext.BeginFigure(firstPoint, true, false);

This seems to work, and we have not found any negative side effects. Not sure why, though...
