Test case

QtWebKit does not properly respond to QInputMethodEvents that have replacement text in them. QInputMethodEvent::setCommitString() takes two integers, the start position (relative to the current cursor position) and the length which should be replaced. The attached test case displays the problem:

1. Launch the application.
2. After five seconds (giving Google time to load), a timer launches which produces events.
3. The text in the input field after 5 seconds should be "ok", not "okX".

If you change to a QLineEdit by flipping the #if 1, the program works.

This is a very important fix for Nokia N8 when using Vietnamese language pack, because replacement text is used extensively in their input methods.
