This isn't a bug.

The common dialog's widgets are native widgets. Each native widgets shares an IME context in top level window, however, the composition transaction continues on the new focused widget. This is a natural behavior on Windows Vista and earlier (I'm not sure why Win7 changes the behavior).

On the other hand, our editors are not native widgets. They share an IME context in each top level window, this is same, however, some resources in our XP level code share the IME related information in process level. Therefore, when focus is switching, we need to commit the composition string forcibly.

This is the reason of the difference between native widgets and our widgets.

Note that after bug 569023, our editor doesn't commit the composition string when it loses focus and another application (including desktop) gets focus. When another our widget gets focus, the composition string is committed forcibly on the old focused editor.
