title: IE11+vue.js: <input type="checkbox" v-on:input="blabla()"> doesn't work/fire
body: <p>A vue.js template containing this doesn't fire in IE11:</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;input type="checkbox" v-on:input="blabla()"&gt;
  </code></pre>
  
  <p><code>blabla()</code> <em>is</em> called in Firefox and Chrome - just not in IE11.</p>
  
  <p>Why is that? See this <a href="https://codepen.io/pmorch/pen/joRxjv" rel="nofollow noreferrer">codepen</a> to reproduce. In IE11, you'll need the <a href="https://s.codepen.io/pmorch/debug/joRxjv/NjkYzqgqvXNM" rel="nofollow noreferrer">codepen debug view</a> though, as the codepen editor is not supported in IE11.</p>
  
  <p>Using vue 2.6.10, which today is the newest version.</p>
