Version

Link to Minimal Reproduction

https://codesandbox.io/s/stacked-line-chart-forked-jfpn79?file=/index.html

Steps to Reproduce

1. Open the link
2. When you hover on the MarkLine component, the tooltip is not displayed but only the ones of the line series

Current Behavior

When you hover on the MarkLine component, the tooltip is not displayed but only the ones of the line series

Expected Behavior

I expect the markLine to be shown even on markLine. This happens when you set the tooltip. trigger equal to item for example.

Environment

- OS:
- Browser:
- Framework:

Any additional comments?

not-a-bug The Expected Behavior is not confirmed by the documentation. There is no statement saying that trigger: "axis" should output the same info as trigger: "item". Therefore you are asking for a new [Feature].
