Bug 501098

SUMMARY

In Falcon's location bar, only first symbol (or first IME candidate) is entered correctly, and then:

* "Ctrl + Space" keybinding does nothing instead of cycling input methods (note: this keybinding is not default).
* "Super + Space" keybinding emits a space character instead of cycling input method groups (note: this keybinding is not default).
* Every next character is typed not using the current input method, but with the system keyboard layout configured in Fcitx for the current group.

Web search bar also has this issue, but to the lesser extent. I can type more characters before this issue appears.

STEPS TO REPRODUCE

Type "asdf asdf" in the location bar.

Case 1: Current input method is "Russian" keyboard, system keyboard layout configured for its Fcitx group is also Russian.
Case 2: Current input method is "Russian" keyboard, system keyboard layout configured for its Fcitx group is English (US).
Case 3: Current input method is Pinyin, system keyboard layout configured for its Fcitx group is English (US).

OBSERVED RESULT

Case 1: фыва фыва
Case 2: фsdf asdf
Case 3: 爱上对方asdf 

EXPECTED RESULT

Case 1: фыва фыва
Case 2: фыва фыва
Case 3: 爱上对方爱上对方

ADDITIONAL INFORMATION

I configured Fcitx5 on Wayland using this guide:
https://fcitx-im.org/wiki/Using_Fcitx_5_on_Wayland

I have two groups:

1) Group 1:

System keyboard layout: "English (US)"

Enabled input methods:
a. "English (US)" keyboard
b. Pinyin

2) Group 2.

System keyboard layout: also "English (US)", so keybindings still work no matter what group is currently active.

Enabled input methods:
a. "Russian" keyboard
