fix: check event cancelable before preventDefault

Avoid issues on mobile where an error is triggered when calling
preventDefault on an event that cannot be cancelled.

Fix these kind of error messages:

[Intervention] Ignored attempt to cancel a touchmove event with
cancelable=false, for example because scrolling is in progress and
cannot be interrupted.
