Describe the issue

When hovering line annotation the line annotation's tooltip doesn't show up. Only while hovering the marker the tooltip appears.
Even with the hideLinesTooltips set to false and high zIndex.
I also tried to disable tooltips with <Tooltip customTooltip={() => null} /> to ensure that tooltip with the value doesn't hide the annotation tooltip, but it didn't solve the issue.

To Reproduce
See this codesandbox.
Steps to reproduce the behavior:

1. Hover over line annotation
2. Hover over marker

Expected behaviour
I would expect to see the line annotation tooltip when we hover over line.
