Element: webkitmouseforcewillbegin event

Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

Safari for macOS fires the non-standard webkitmouseforcewillbegin event at an Element before firing the initial mousedown event.

This offers the opportunity to tell the system not to trigger any default Force Touch actions if and when the click turns into a Force Touch event.

To instruct macOS not to engage any default Force Touch actions if the user apply enough pressure to activate a Force Touch event, call preventDefault() on the webkitmouseforcewillbegin event object.
