Describe the bug
When mousing over the legend the currently hovered series stays at full opacity while the other series reduce opacity. However when the non-hovered series is a LineSeries, only the line's opacity reduces, the dot stays at full opacity.

To Reproduce
Steps to reproduce the behavior:

1. Create a chart with several LineSeries
2. Hover legend

Expected behavior
The dot and the line should be grouped and then whole group's opacity should be reduced
