### The Problem

I have a chart that can be toggled on/off( show or hide) upon clicking its legend(VictoryLegend). After updating my package from 35.4.8 to the latest victory library package, my events seem to have disappeared after initial interaction. I am unable to toggle my chart continuously. i can only do it once

Initial render:(my sharedEvents exist)

After initial interaction( toggle once):
sharedEvents props disappeared

Downgrading my victory version back, seems to enable my toggle event to work again. Is there any breaking changes from 35.4.9 onwards with regards to how events are supposed to be used? Or am i using handling events wrongly?

Any help would be much appreciated :)
