Android Studio: How to prevent zooming while typing?

Question

Android

webview, android studio.
A webview loads a page that has the viewoport meta tag:

<meta name="viewport" content="width=700, user-scalable=no, maximum-scale=1.0" />

Despite maximum-scale=1.0 , when the text input field is in focus, the scale is increased (for ease of input, apparently). Due to user-scalable=no , it is not possible to return the scale "to its place", and I do not at all need the scale to increase when entering text.
How to deal with this problem?
Thank you in advance!
