Cannot render 50 or more series with specified colors and enabled boost

[rdp1414]

As suggested by michal.f in forum Topic#50030, I'm logging this bug issue.

Chart points are not rendered when:

1. Boost module is enabled.
2. Color is specified in input.
3. Number of series is greater than or equal to 50.

Our business-use-case involves displaying more than 50 series with specific colors. Can you please fix the bug / give us some workaround / tell me if I'm doing anything wrong here?

Expected behaviour

All series with data points with "grey" color should be correctly rendered.

Actual behaviour

None of the data-points are rendered.

Hi @rdp1414!

From what I can see this issue is only visible for the color grey as a workaround you can use different spelling gray -demo.

Internal note:
grey can be added to the defaultHTMLColorMap.
