#4 Typed characters disappear when moving mouse (Ubuntu/IBus-Mozc)

[Nicolas Raoul]

Characters sometimes disappears on Firefox:

1. Enable IBus-Mozc to type in Japanese
2. Type some Japanese characters and put the mouse on them to have Rikaisama show its blue popup
3. Type g
4. Type a. The character が appears. Don't type Enter.
5. Move the mouse
6. The character disappears

Notes:

• It only happens when Rikaichan (or Rikaisama) is activated
• It only happens on some text areas, not all. Facebook's chat box has the problem, as seen above
