some traditional Chinese words can only be entered if simplified Chinese is also enabled

In settings there is 'Chinese mode' with 5 options:
- Simplified Chinese,
- Traditional Chinese,
- Simplified Chinese before Traditional Chinese,
- Traditional Chinese before Simplified Chinese, and
- All Chinese characters

If traditional Chinese only mode is selected, some traditional characters common to both traditional and simplified Chinese cannot be entered.

eg. using CangJie5 and 'Traditional Chinese' only mode
- entering ‘RC’ (口金) only suggests 「叭」 and 「唫」. 「只」 is not available
- entering ‘EYG’ (水卜土) only suggests 「塰」. 「注」 is not available
In any other mode that include simplified Chinese characters, 只 and 注 are listed in suggestions as expected.

When using Quick5 and 'Traditional Chinese before Simplified Chinese' mode, simplified characters are outside of the 100 character suggestions limitation. Resulting in 「只」 and 「注」 not showing up in suggestions at all.

ibus-table-cangjie5 1.8.2-1

P.S. cangjie code for 塰 should be 水十土 or 水卜十土, not 水卜土. But that's a completely unrelated issue.
