Statistics tab resets when resizing the Minecraft window

When resizing the Minecraft window or enabling/leaving fullscreen mode while in the statistics screen, the tab resets to "General".

This was previously part of MC-258, but when that was fixed, this issue was apparently not part of that fix.

To reproduce

1. Open the statistics menu
2. Click on "Items"
3. Resize the Minecraft window
   → You're back in "General"
