disable viewport zooming iOS 10+ safari?
<p>I've update my iPhone 6 plus to iOS 10 beta version and just found that in mobile safari, you can zoom any webpages by double tapping or pinching <strong>IGNORE</strong> the <code>user-scalable=no</code> code in the meta tag. I don't know whether it's a bug or feature. If it's considered as a feature, how do we disable viewport zooming iOS 10 safari ?</p>

<p>updated on iOS 11/12 release, iOS 11 and iOS 12 safari still DO <strong>NOT</strong> respect the <code>user-scalable=no</code> meta tag.</p>
