- Don't show the progress icon unless loading from network
- Don't show the content until LoadAttachmentsTask finishes
- Disable the fade-in animation. It causes some weird positioning issue
with the GL accelerated webview.
- Use WebView.clearView() to clear its content.
- Use the "normal" layout mode, otherwise WebView won't use its entire
width
- Don't hide the vertical scrollbar
