Currently, when an element has only a hover listener, the attached listener will never trigger, because within the check for whether a hitbox has to be inserted for the given element, this case it not considered. That leads to the behaviour as described in https://github.com/zed-industries/zed/pull/25602#discussion_r1970720972, where another event listener has to be attached to the element in order for the hover listener to work. This PR fixes the issue by ensuring that a hitbox is also inserted when only a hover listener is attached to the element. Release Notes: - N/A
