<p dir="auto">I have a dialog with a table in it that requires scrolling. The table contains a column that contains icons with tooltips. Everything is okay when tooltip placement='bottom'. When I change placement to 'right' an additional scrolling bar appears inside the dialog.</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/callemall/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">Same as with Tooltip placement='bottom'</p>

<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"><code class="notranslate">&lt;Switch checked={this.props.isChecked}  /&gt;</code><br>
When this.props.isChecked is <strong>undefined</strong>( on initial render), the switch is off.  When this.props.isChecked later updates to <code class="notranslate">true</code>, the switch should be on.</p>
<h2 dir="auto">Current Behavior</h2>
<p dir="auto">When initial value is <code class="notranslate">true</code> or <code class="notranslate">false</code>, everything works as expected.  When initial value = <code class="notranslate">undefined</code>, later updates do not show</p>

<p dir="auto">In the sample, both switches should become <code class="notranslate">true</code> after timeout of 2000.  checkedA with initial value of false works,  checkedB remains unchecked.</p>
<h2 dir="auto">Context</h2>
<p dir="auto">Checked prop should be Boolean or String, but sometimes initial values are undefined until server data arrives.  a <code class="notranslate">!!checkedB</code> resolves the issue, but it can be very confusing.</p>
