According to this https://bugs.webkit.org/show_bug.cgi?id=88047 WebKit dropped the support for target-densitydpi from viewport params. Unfortunately, the bug description states neither the motivation for the change, nor the workaround.
Certain web-pages that wanted to prevent scaling on mobile devices had the following declaration of the viewport:
<meta name="viewport" content="width=device-width,
initial-scale=1.0, maximum-scale=1.0,
user-scalable=no, target-densitydpi=device-dpi"/>
Now this code outputs an error in Chrome (tested with 21.0.1180.49 beta-m). Please advice what is the supposed way to make a web-page without the error messages and retain the same behavior as before with target-densitydpi=device-dpi"
