webView on android does not adjust zoom level correctly after calling "back()" function

Hi

I use the newWebView component on my app. 

At the first page, I load my offline HTML file. My html files also contains the links that load the content from the Internet. It works fine, if the target site is mobile site. However, if the target site is not a mobile site, when I call webView:back(), haft of my offline html file is disappeared. 

I have to zoom in-out the view to make the content back.

I have try webView:reload(). I fixed the issue, but the history will be clear, and webView.canGoBack will never be equal to false which I need it for trigger other events.

I seem to happen only on Android device but not IOS device.

Anything I can do for this ?

Thank you
