Description

When the down arrow is pressed on the last element in the dropdown, the control attempts to setHovered on an item one past the end of the list (it sets index wrong):

        keyArrows(direction) {
            const sum = direction === 'down' ? 1 : -1
            if (this.isActive) {
                let index = this.data.indexOf(this.hovered) + sum
                index = index > this.data.length - 1 ? this.data.length : index
                index = index < 0 ? 0 : index

                this.setHovered(this.data[index])

should be:

        keyArrows(direction) {
            const sum = direction === 'down' ? 1 : -1
            if (this.isActive) {
                let index = this.data.indexOf(this.hovered) + sum
                index = index > this.data.length - 1 ? this.data.length - 1 : index
                index = index < 0 ? 0 : index

                this.setHovered(this.data[index])
