Description

I'm using this vendor[1] to set all event as passive event. Ui-grid work more fast than early and fine like always, but i get this error on console:

Unable to preventDefault inside passive event listener invocation:   | preventDefault | @ | ui-grid.js:11956   | (anonymous) | @ | ui-grid.js:2856   | mousewheelHandler | @ | ui-grid.js:11967

I'm searching some idea to avoid it.

Contributor guide

Research direction
Investigate the default passive events library and how ui grid calls preventDefault on touch or wheel events. Look for passive listener violations in ui grid's event handlers (specifically around mousewheelHandler). Consider adding {passive: false} option in addEventListener calls where preventDefault is needed, or wrap with a flag to disable passive behavior.
