Let me add little fix, to allow forceZIndex = 0. Check whether forceZIndex is assigned with isNaN(). Any numeric should be considered as good value.

    _updateZIndex: function(offset) { // offset at relative value, or put absolute zIndex value with forceZIndex
        this._icon.style.zIndex = isNaN(this.options.forceZIndex) // any no-numeric = unassigned. 0 is ok for the forceZIndex
            ? (this._zIndex + offset)
            : (this.options.forceZIndex + (this.options.zIndexOffset || 0))
    },
