Avoid clipping tooltip markers on edges

[markov00]

Find a way to fully display tooltip markers near the edges.

Kibana Cross Issues:

• Line chart can clip or fail to show point at the top of the range kibana#13248

[markov00]

The same also happens for points near the edges, with some particular curve types for lines/areas

Hi @markov00,
Thanks for writing this down.
Just a note that I've got the same issue to the y tick as well.

Can we boost this one in priority?
