IBus 1.5.21 Chinese input in Ubuntu 19.10 not working with Atom 1.45.0 as snap

[ytxmobile98]

• OS: Ubuntu 19.10
• IBus version: 1.5.21
• Atom version: 1.45.0

When I switch to Chinese input mode (Intelligent Pinyin) and try to type Chinese into Atom 1.45.0 (snap version), it simply doesn't work. When I type the letters into the window, it shall bring up the candidate list for me to pick words. But instead, the letters are directly typed into the window, but not Chinese characters.
