I had the same problem and found the solution from Vocaro's post to solve the problem!

"Add the following meta tag to your HTML document's head:

<meta name='viewport' content='initial-scale=1.0,maximum-scale=10.0'/>"

so basically for you

"<meta name='viewport' content='initial-scale=1.0,minimum-scale=1.0, maximum-scale=2.0'/>" 

should do the trick.
