[Lens] Can't enable chart context menu if the tooltip is too close to the bottom of the screen

[markov00]

Kibana version:
main

Describe the bug:

Trying to use right-click on a geometry that is too close to the bottom of the screen could fail opening the context menu due to the scroll bar appearing and disappearing quickly and making the context menu disappear immediately.

Steps to reproduce:

1. create a stacked bar chart with more then 10 elements
2. try to right-click on a bar that is close to the bottom of the screen (from within Lens editor)
3. you will notice that the screen will flick for a frame and the context menu will not appear.

Expected behavior:
The context menu should pop up on a different position but should appear anyway.

Any additional context:

Hiding the body overflow help a bit, but the tooltip should recompute its position when open in context menu (cc @nickofthyme )

The same behaviour is also visible in dashboard

@markov00 is this something that can be fixed in kibana?

[markov00]

not fully sure, I believe this could be half charts half Kibana. Kibana has always this scrollable body where we don't actually need it, so probably we need to double-check this too.

Huh that's strange, never seen that before. Popper should be able to place the tooltip no matter the scroll container. I think we need to solve this in charts. @markov00 the pinned state does not change, it's set to true flickers and goes on thinking the tooltip is not pinned, then clicking out of the chart blurs the tooltip and sets pinned to false.

Also tried setting fallback placements and that does nothing to resolve this.
