[regression] Pokerstars partially broken since 2455

[bugsan]

Since version 2455 (and in latest 2458), some tabs are empty. I think it's all tabs using a WebView. The other "native" tabs are still working fine.

Here is what it should look like (with last working version 1.2.2.2390)

I believe it's related to WebView because all tabs affected are using a WebView (Spin&go, Sport, etc...)
