Users must be able to magnify the contents of a web page by up to 200%. In modern 
browsers this is almost always possible unless the page chooses to disable it.

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:

```html
<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.
