Line chart / trend line - Uncaught TypeError: d.points[c] is undefined

[Philipp Förmer]

Hi,

I use a line chart with a linear trend line.

Example code: https://jsfiddle.net/philipp_foermer/q2c4ajr1/3/

If the mouse is hovered over the trend line, then randomly after some time the following java script error appears and the chart view is stuck (no hover tooltip anymore for a data point). If no trend line is used, then the issue does not occur.

Uncaught TypeError: d.points[c] is undefined

Any ideas, if this is an issue in the library or my code misses something?
