Does it work?

Does this add-on still work? Looks like the mouse event listeners are not created.

{{yield (assign
    dd
    (hash
      trigger=(component dd.Trigger
        onMouseDown=(action "prevent")
        onMouseEnter=(action "open")
        onMouseLeave=(action "close"))
      content=(component dd.Content
        onMouseEnter=(action "open")
        onMouseLeave=(action "close")
      )
    )
  )}}

Here's what I did

ember g component basic-dropdown-hover -gc

import Component from '@glimmer/component';
import { tracked } from '@glimmer/tracking';
import { cancel, later } from '@ember/runloop';
import { action } from '@ember/object';
import { oneWay } from '@ember/object/computed';

export default class BasicDropdownHoverComponent extends Component {
    @tracked delay = 300;
    @tracked closeTimer;
    @tracked openTimer;
    @oneWay('delay') openDelay;
    @oneWay('delay') closeDelay;

    @action open(dropdown) {
        if (this.closeTimer) {
            cancel(this.closeTimer);
            this.closeTimer = null;
        } else {
            const openFn = () => {
                this.openTimer = null;
                dropdown.actions.open();
            };

            const { openDelay } = this;

            if (openDelay) {
                this.openTimer = later(openFn, openDelay);
            } else {
                openFn();
            }
        }
    }

    @action close(dropdown) {
        if (this.openTimer) {
            cancel(this.openTimer);
            this.openTimer = null;
        } else {
            const closeFn = () => {
                this.closeTimer = null;
                dropdown.actions.close();
            };

            const { closeDelay } = this;

            if (closeDelay) {
                this.closeTimer = later(closeFn, closeDelay);
            } else {
                closeFn();
            }
        }
    }

    @action prevent() {
        return false;
    }
}

    {{yield (assign dd
