Google Maps Onebox data is not cached

I am still struggling with this, how can the onebox gem fix it.

This markup is cached fine:

<div class="regular contents"><div class="cooked"><p>Test case: <a href="https://goo.gl/maps/R6nj3Qwf2LR2" rel="nofollow noopener">https://goo.gl/maps/R6nj3Qwf2LR2</a></p>

<div class="maps-onebox">
<div style="background:transparent;position:relative;width:690px;height:400px;top:400px;margin-top:-400px;"></div>
<iframe src="https://maps.google.com/maps?ll=51.5332441,-0.1281903&amp;z=17&amp;output=embed&amp;dg=ntvb&amp;q=Google+UK" width="690" height="400" frameborder="0" style="border:0">&amp;lt;img src="https://maps.googleapis.com/maps/api/staticmap?maptype=roadmap&amp;amp;amp;center=51.5332441,-0.1281903&amp;amp;amp;zoom=17&amp;amp;amp;size=690x400&amp;amp;amp;sensor=false" width="690" height="400"&amp;gt;</iframe>
</div>

<p>Rendering this onebox issues <strong>10</strong> network requests in sequence every time.</p></div><section class="post-menu-area clearfix"><nav class="post-controls clearfix"><div class="actions"><button class="widget-button toggle-like like no-text" aria-label="like this post" title="like this post"><i class="fa fa-heart" aria-hidden="true"></i></button><button class="widget-button share no-text" aria-label="share a link to this post" title="share a link to this post" data-share-url="/t/bug-google-maps-onebox-data-is-not-cached/59124?u=sam" data-post-number="1"><i class="fa fa-link" aria-hidden="true"></i></button><button class="widget-button show-more-actions no-text" aria-label="show more" title="show more"><i class="fa fa-ellipsis-h" aria-hidden="true"></i></button><button class="widget-button reply create fade-out" aria-label="begin composing a reply to this post" title="begin composing a reply to this post"><i class="fa fa-reply" aria-hidden="true"></i>Reply</button></div></nav></section></div>

Is there an option to amend the markup so somehow the iframe stops it barrage of requests and uses a local cache or something?
