iOS 7 no longer allowing pages to be non-zoomable with tag?

iOS 7 no longer allowing pages to be non-zoomable with tag?

I've been using the following to keep the mobile version of my website
from being scalable/zoomable:
<META content="width=device-width; initial-scale=1.0; maximum-scale=1.0;
user-scalable=0;" name="viewport" />
After I updated my phone to iOS 7, I noticed that you can now zoom to your
heart's content. (This is true in both Mobile Safari and Chrome for iOS.)
This change has wreaked some havoc on the layout, and I'd rather not have
to have separate stylesheets for each iteration of the OS. Is there an
alternative method to disabling zooming on mobile devices? Thanks.
