Twitter Widget ignoring data attributes?


I have the following markup, which should remove both the header and footer on my feed through data-chrome and a few other things.

<a class="twitter-timeline" data-dnt="true" href="" data-widget-id="345452670653456385" data-border-color="#FFFFFF" LANG="SV" data-chrome="noheader nofooter transparent noborders noscrollbar" data-tweet-limit="4">Tweets av @skaneleden</a>
<script>!function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0],p=/^http:/.test(d.location)?'http':'https';if(!d.getElementById(id)){js=d.createElement(s);;js.src=p+"://";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs");</script>

This code used to work fine, until yesterday when I noticed that the widget was ignoring all my attributes. Now it looks like this:

*** UPDATE ***

Well turns out that I was running Chrome Canary (v.30) at the time and was to silly to test it in other browsers. It’s working again in Chrome Canary 30.0.1562.0. Sheeeeet!
