95 Zooming and scaling must not be disabled

Users with partial vision and low vision often choose to enlarge the fonts on their browser to make text on the web easier to read. The browser's viewport focus is everything visible in the browser window at a given moment. If the user maximizes the browser to full size on a high-resolution monitor, the viewport focus area is large and may include the entire web page.

Ensure that the user-scalable="no" parameter is not present in the <meta name="viewport"> element and the maximum-scale parameter is not less than 2.
