User-scalable = no not working, is it supported?

Question

I am working on a site. I need to prevent scaling animations when the user selects a form, however I am trying with this code

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

and it does not work. I can’t find anything, it seems that I'm the only one who has encountered this problem. Is it supported in new versions of iOS? Most of the posts I found are pretty old

Landed on this post having the same problem. It turned out that it seems to be required to have the css width specified in the html and / or case. At least he started working by adding this
