<h2 dir="auto">Context</h2>
    
<p dir="auto"><code class="notranslate">Menu</code> <a href="https://github.com/callemall/material-ui/blob/v1-beta/src/Menu/Menu.js#L189">intercepts <code class="notranslate">classes</code> prop</a>, so it is not passed to <code class="notranslate">Popover</code> component along with <code class="notranslate">...other</code> props.<br>
My suggestion would be adding <code class="notranslate">PopoverProps</code>, which then can be used to pass <code class="notranslate">classes</code> prop to <code class="notranslate">Popover</code> (like it is implemented in <a href="https://github.com/callemall/material-ui/blob/v1-beta/src/Drawer/Drawer.js#L246">Drawer</a>).<br>
I can submit a PR if you are OK with this solution</p>
