I tested it with the latest version on Oneiric and it works like
expected. The pre-edit stuff appears in the search field, so you can see
what you type.

I tested with ibus-hangul (Korean), ibus-anthy (Japanese) and
ibus-pinyin (Chinese).

The difference you described is the following: in hangul, you compose
the syllables out of letters, like you described. There is no ambiguity,
each syllable is unique. Therefor ibus submits the syllable when it's
complete. Means, either you press Space or Enter to signal that the
syllable is complete, or you start typing a new syllable, where ibus
knows that the last component you typed can't be part of the syllable
you typed before and therefore must be part of a new syllable.
In Japanese and Chinese however, things work differently. Since we type
the pronunciation and each pronunciation can map to multiple characters
(words), we need to choose which characters we want. The input engines
nowadays are smart enough to select the correct characters for whole
sentences, by context search. Therefore we type the complete sentence in
the pre-edit phase and review if the engine has chosen the correct
characters. We can go back with the arrow keys and correct any wrongly
chosen characters.
Only when we are satisfied we submit the whole string with either Enter
or Space, depending on the input method.

Hence, the scenario you described is expected. Nothing wrong with it. :)

Cheers
Arne
