title: Firefox not recognizing a link registered by the vue eventhandler in older Firefox
body: <p>I do have a following HTML code:</p>
  
  <pre><code>&lt;button id="btncontinue" ref="btncontinue" v-on:click="oncontinueclick" v-show="continuevisible"&gt;
  &lt;i class="fa fa-arrow-alt-circle-right fa-2x continue-icon"  v-show="continuevisible"&gt;&lt;/i&gt;
  &lt;/button&gt;
  </code></pre>
  
  <p>oncontinueclick fires registered method in the vue app. It works fine in the last browsers.
  However, there is an odd problem with older browsers. I have to make it work for FF 45.9 and newer.
  On FF 52 i experienced following problem - there are no script errors, but the button itself is not clickable (It's not even showing a hand cursor like on FF 7x, icon and the button are just the part of the background). It's like the eventhandler is not recognized, but in the inspector i see events attached, they even redirect to vue invoker, so it seems that FF has no problems with the scripts.</p>

  <p><code>&lt;i&gt;</code> element wasn't originally clickable, i just made it so for tests purposes. Is there any workaround? Or is this simply my error?</p>
  
  <p>Vue version: 2.6.11 (but also 2.5.13)
  There a bootstrap linked (without js)
  and Axios (0.19.2)</p>
