<h1>Debounce + later coelessing</h1>
<p style="color: blue">
Since Ember 3.4, debounce and later seem to coalesce in a way that they didn't in 3.3 (see <a href="https://github.com/BackburnerJS/backburner.js/pull/319">this PR</a>)
</p>
Try these:
<button {{action 'case1'}}>debounce@1000, later@2000</button>
<button {{action 'case2'}}>later@2000, debounce@2000</button>
<hr>
<ul>
{{#each this.logs as |log|}}
<li>{{log}}</li>
{{/each}}
</ul>
