How to disable the context menu on long press when using device mode in Chrome?

Question

How to disable the context menu on long press when using device mode in Chrome ?

I mean this context menu:

I am asking this because I want to debug long press gestures for mobile devices and the context menu causes my react app to behave in a strange way:

when I try to reorder the list then "strange things start to happen": selected item starts to float all over the place (as can be seen from snapshot below). The Hello World is obscured by the selected item. Really strange.

I have developed a slightly more "advanced" workaround that will still (most of the time) show the contextmenu on right-click while preventing it from showing on a simulated long-tap:

window.oncontextmenu = function() {
    if (event.button != 2 && !(event.clientX == event.clientY == 1)) {
        event.preventDefault();
    }
}
