title: Pass parameter from v-for to dynamically update b-tab title
body: <p>Only about 6 weeks into using vuejs and haven't looked at components at all, so sorry if this is a dumb question.</p>
  
  <p>I am attempting to make the b-spinner component for tabs from <a href="https://bootstrap-vue.js.org/docs/components/tabs/" rel="nofollow noreferrer">bootstrap-vue</a> update dynamically inside a v-for loop, with the parameter from the v-for being past to a computed property.</p>
  
  <p>It works fine when not in a v-for.</p>
  
  <pre><code>&lt;b-tab&gt;
    &lt;template v-slot:title&gt;
       &lt;b-spinner type="border" small v-show="!updateDone"&gt;&lt;/b-spinner&gt; &lt;strong&gt;Tab Title&lt;/strong&gt;
    &lt;/template&gt;
    ...
  &lt;/b-tab&gt;
  </code></pre>
  
  <p>But when I try to pass the player property from the v-for, it breaks. When I try to pass <code>player</code> to the title slot, the entire parent component gets passed.</p>
  
  <pre><code>&lt;b-tab :key="player['player-id']" v-for="player in updatePool"&gt;
    &lt;template v-slot:title="{player}"&gt;
      &lt;b-spinner type="border" small v-show="!updateDone(player)"&gt;&lt;/b-spinner&gt; &lt;strong&gt;{{player['player-name']}}&lt;/strong&gt;
    &lt;/template&gt;
    ...
  &lt;/b-tab&gt;
  </code></pre>
  
  <p><code>updateDone</code> is a computed property as follows:</p>
  
  <pre><code>updateDone: function (player) {
    return _.every(Object.values(this.someObject[player['player-name']]), Boolean)
      },
  </code></pre>
  
  <p>But <code>updateDone</code> is never returned b/c <code>player</code> is an entire Vue object (presumably the parent component)</p>
  
  <p>Hoping for some insight on this.</p>

    &lt;/template&gt;
