Login WebView refreshes content after device orientation change

[littlecd]

Click several links in Login WebView and then rotate screen. The web page refreshes back to the login page. But the content should persist.

Before rotation

After rotation

我们建议你使用一下谈坛试试？因为我们要兼容iOS和Android的用户（因为Apple天价的membership fare有投放广告），所以目前不会把太多心力放在维持discuzhub上。

Thanks for your update, maybe I can try a fix? I will pull a request later.
