Describe the bug
Looks like onElementClick event works only if pointer position during mousedown event is the same as during mouseup event. If mouse pointer is moved during click, then onElementClick interaction isn't firing. This seems to be different from native browser behaviour, where click events are still recognised if mouse pointer is moved. This difference makes clicks in elastic charts flaky when using a mouse, because start-end positions could be different when clicking while the mouse in motion.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://elastic.github.io/elastic-charts/?path=/story/interactions--sunburst-slice-clicks
2. Mousedown in one of the slices.
3. Slightly change pointer position, leaving the mouse in the same slice
4. Mouse up
5. See onElementClick didn't fire

Expected behaviour
OnElementClick interactions fires

Version (please complete the following information):

• OS: Mac
• Browser: Chrome 83
• Elastic Charts: 27.0.0

Additional context

Noticed while working in a kibana dashboard.
