Trackpad pinch-to-zoom event not fired in Zoom apps

Zoom Apps
1

Hi,

Adding an event listener on the wheel event does not work in Zoom apps for pinch gestures done using the trackpad:

htmlElement.addEventListener('wheel', event => { console.log('Never fired') })

On regular browsers, when using a laptop’s trackpad, users can pinch to zoom in or out which results in a wheel event with event.ctrlKey = true. In Zoom apps this event is not fired at all (but all the other gestures work).

This can be reproduced by creating a Zoom app pointing on this JS fiddle : https://jsfiddle.net/0bpw492y/ (allow the domains jsfiddle.net and fiddle.jshell.net in Domain Allow List).

This is a problem for us because our app is highly interactive and users cannot zoom in/out with the trackpad alone.

Is this a known issue?

I forgot to say that this is an issue on Windows only, macOS works as expected.
