<p dir="auto">When a tab control is first mounted there is an animation of the indicator to the first selected index.</p>

<ul class="contains-task-list">
<li class="task-list-item"><input type="checkbox" id="" disabled="" class="task-list-item-checkbox" checked=""> I have searched the <a href="https://github.com/mui-org/material-ui/issues">issues</a> of this repository and believe that this is not a duplicate.</li>
</ul>
<h2 dir="auto">Expected Behavior</h2>

<p dir="auto">The tab indicator should not animate to the first tab index, it should already be there.</p>
<h2 dir="auto">Current Behavior</h2>

<p dir="auto">The tab indicator is animated until it reach the first selected index.</p>

<p dir="auto">I came up with a simple idea to make material-ui exportable as bootstrap 3/foundation 5 extension so it will be possible to apply material-ui colors, addons and overrides to these frameworks.</p>
