Disable pinch-to-zoom in iOS 10 in Cordova/Phonegap app -

i have mobile app build phonegap (cordova) , app live on app store, new feature of ios10 beta:

to improve accessibility on websites in safari, users can pinch-to-zoom when website sets user-scalable=no in viewport.

make app zoomable , totally broke design of app when zoomed.

maybe feature websites on mobile (or not), want able disable hybrid mobile app

this how viewport looks in index.html

<meta name="viewport" content="user-scalable=no, initial-scale=1, maximum-scale=1, minimum-scale=1, target-densitydpi=medium-dpi, width=device-width, height=device-height" /> 

is there known solution resolve problem new ios released soon?

i using wkwebview and

<engine name="ios" spec="~3.9.2" /> <preference name="phonegap-version" value="cli-5.2.0" /> 

update

i updated phonegap version 6.3.0 , ios platform version 4.1.1 , have same error.

<meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width">
