Ensure pinch-to-zoom is enabled

Websites should avoid using the meta viewport tag to disable pinch-to-zoom. This behavior is highly discouraged for accessibility and usability on mobile devices.

Generally the code causing this issue looks like this:

<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no" />

Here the use of user-scaleable=no asks the browser not to allow user zoom.

iOS no longer allows websites to disable pinch-to-zoom, and ignores this part of the viewport tag. Therefore to replicate this issue you must use an Android device.
