This problem has started with r15429: <rdar://problem/4614054> REGRESSION:
Safari submits forms when the Return key is hit to complete inline inputs.

WebCore tries to second-guess the input method, which may or may not let the
keypress propagate. This particular heuristic happens to match Kotoeri, but not
other IMs, so form submission is performed too late, when two(!) linefeeds are
already appended to the value. Potentially, similar problems can affect any
keys that are custom processed by WebCore, not just Enter.

For IMs to do their work properly, events first need to be filtered through
-[NSResponder interpretKeyEvents:], with the real work being done from
NSTextInput callbacks, rather than from keyUp/keyDown. Of course, this can
cause lots of issues with HTML events (e.g. whether onkeydown/onkeypress
handlers should be called, or whether they can cancel the event).
