Keymap change for DirectInput mode and IMEOn command requires fcitx5 restart

[jubame]

Description

Keymap change for DirectInput mode and IMEOn command requires a fcitx5 restart. However, non DirectInput modes keymap changes do not require a restart.

Steps to reproduce

Steps to reproduce the behavior:

1. Go to Mozc -> Configure -> Configuration Tool -> Configure -> Keymap section -> Keymap style MS-IME -> Customize...
2. Go to this default row: DirectInput mode - Hankaku/Zenkaku key - IMEOn command
3. Change key from default Hankaku/Zenkaku to something else.
4. This message is shown: "Changes of keymaps for direct input mode will apply only to applications that are launched after making your modifications." -> Click OK

Expected behavior

Either of these:

• No restart required
• Automatic restart
• Manual restart: in this case, ask the user to restart fcitx5 manually in the dialog box at point 4 above, instead of restarting the application.

Actual behavior

Pressing the keymap does nothing, staying in DirectInput mode, even after restarting my editor. Have to restart fcitx5 manually for it to take effect.

Investigations

• Whether this issue happens on both Ibus and other IMF (e.g. Fcitx, uim).
  • N/A, only tried fcitx5
• Whether this issue happens on other IMEs (e.g. Anthy, SKK).
  • N/A, only applies to Mozc
• What applications this issue happens on (e.g. Chromium, gedit).
  • I have tried Firefox and Mousepad
• What applications this issue does not happen on (e.g. Chromium, gedit).
  • not-found
• (optional) What versions or commit-ids this issue did not happen on
  no-investigation, this is the latest package for my distro.
