           Summary: Keyboard layout does not change when input source
                    language changes
           Product: Fedora
           Version: 21

Description of problem:
The keyboard layout changes for Japanese when input source changes from English
US to Japanese (plain). However, the layout won't change when input source
changes from English US to Japanese Kana Kanji. The layout remains for English.

Version-Release number of selected component (if applicable):
ibus-1.5.8-1.fc20.x86_64

How reproducible:
Always

Steps to Reproduce:
(I assume GNOME Desktop)
1. Open the settings panel (gnome-control-center)
2. Select [Region & Language]
3. Add English US and Japanse Kana Kanji to the input source list
4. Press Supser+Space to switch the input source to English US
5. Press Supser+Space to switch the input source to Japanese Kana Kanji

Actual results:
The keyboard layout remains for English US.

Expected results:
The keyboard layout is for Japanese

Additional info:
This problem also occurs when:
- switching between English US and Japanse Mozc
- switching between German and Japanse Kana Kanji

This problem does NOT occur when:
- switching between English US and Japanse (plain) 
- switching between English US and German

And this problem occurs on Fedora 21, too
