Comment 8 for bug 1829947

The steps are not so clear, doing this, under GNOME (normal Ubuntu session)
- install ibus-libpinying and language-pack-gnome-zh-hans
- go to control center -> region and configure "chinese (inteliggent pinyin)"
- open gedit
- select chinese in the indicator
- type "one"
-> some chinese words are suggested
- press + (is that step needed)
-> the selector page change
- press "down" to select the second 'word'

-> try to press + or ',' and nothing happens ... would you expect for the UI to close at this point? Or do you use space to close it and then the char?
Also if '+' is supposed to go to the next page why would you like it to close the popover?

Oh, and the ppa build doesn't seem to change the behaviour for those cases...
