The preedit sent back to the owner was always impre(), the reading, so
かく stayed underlined in the application while the popup showed 書く and
Enter inserted 書く. Nothing was hidden -- the popup had it -- but the
text did not stand where it was going to land, and mozc, fcitx5 and kime
all put the candidate inline.
Only the reply changes. impre() still answers the reading everywhere it
is the reading that is wanted: commitim, the okurigana mark, the seed
Ctrl+H takes, and snapshot, so a popup that draws the preedit itself
keeps the reading above the list where it says something the highlighted
row does not. Consulting im.sel here is safe where consulting it inside
impre() would not be: transstr memsets a local Im, whose sel is 0 and not
-1, and this reply only ever reads the engine's own.
Nothing in the suite pinned the old answer, so the test is new.
