Description Gabe Colburn CLA 2020-01-02 16:04:02 EST 
Scrolling in a TableViewer with scrollbar with the mouse wheel in Chrome 79.0.3945.79 produces a Chrome error behind the scenes as seen in the DevTools:

rap-client.js:24 [Intervention] Unable to preventDefault inside passive event listener due to target being treated as passive. See https://www.chromestatus.com/features/6662647093133312

The stack trace is:
stopDomEvent	@	rap-client.js:24
setDefaultPrevented	@	rap-client.js:49
preventDefault	@	rap-client.js:18
_onClientAreaMouseWheel	@	rap-client.js:143

dispatchEvent	@	rap-client.js:17
_dispatchMouseEvent	@	rap-client.js:47
