<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">Dialog will scroll its own content when I make a scroll gesture on the phone</p>

<h2 dir="auto">Current Behavior</h2>
<p dir="auto">Once I open a second fullscreen modal (which is opened previously by another fullscreen modal), the scroll won't work as expected, since it will scroll contents that are not visible (the Modal behind)</p>

<h2 dir="auto">Steps to Reproduce (for bugs)</h2>
<p dir="auto"><a href="https://codesandbox.io/s/pkjk07o8o0" rel="nofollow">https://codesandbox.io/s/pkjk07o8o0</a></p>
<ul dir="auto">
<li>Open the link on iOS</li>
<li>Go to the second Dialog</li>
<li>Scroll to the very end, scroll two time more while at the end</li>
<li>Once at the end of the modal, scroll to the top</li>
<li>Scroll will start to feel weird.<br>
Note: it seems that this is happening when you scroll tapping on a input, not 100% sure.</li>
</ul>

<h2 dir="auto">Context</h2>

<p dir="auto">I'm trying to go thru a list of Cards on a Dialog, click on a specific one so it will open a edit Modal, trying to add data to the fields on the 2nd modal will feel weird when I try to scroll.</p>

<p dir="auto">Tested dialogs in <a href="http://www.material-ui.com/#/components/dialog" rel="nofollow">http://www.material-ui.com/#/components/dialog</a>.<br>
On desktop Chrome, background scrolling is disabled when dialogs are shown.<br>
However, it is not disabled in iOS Safari or Chrome.</p>
