config.xml / `DisallowOverscroll` preference doesn't seem to be working

[nodefish]

With this plugin the WKWebView seems to ignore the DisallowOverscroll setting in config.xml (<preference name="DisallowOverscroll" value="true" />). It seems to occur immediately after focusing an input, which causes the keyboard to appear and the page to shift upwards. After doing this even just once, the webview becomes permanently overscrollable.

For testing purposes, I switched to the standard WKWebView engine (1.1.3) and the issue did not occur (the webview remained fixed).

This is an awesome plugin and I'd prefer to use this one over the standard one. Thanks!
