fix: create separate handler instances for containers

[r281GQ]

Description

Fixes #2369

When two VoronaiContainers are used the tooltips does not show up / disappear consistently.

See video below:

bug.mp4

Expected behaviour is consistent:

expected.mp4

This PR makes separate instances for every container so no references would be captured in another container.

I'm having a similar issue and need this fix too and came across this PR. Thanks for working on this!

One thing I noticed: doesn't this change break throttling though? We're now creating a new instance of the throttling function each time defaultEvents is called when VoronoiHelpers is instantiated.
