Bug ID: 2254655
           Summary: keyboard is not working KDE App lokalize until swtich
                    window (page up/down and text input)
           Product: Fedora
           Version: 39
                OS: Linux
            Status: NEW
         Component: ibus
          Keywords: i18n
          Severity: medium

  Target Milestone: ---
    Classification: Fedora

Environment: KDE
Application: lokalize (Translation editor)

1) Keyboard shortcut like Page up and Page down is not working in lokalize
application if ibus is active in KDE

2) Input data is not committed without switching application if ibus is used
with lokalize.

If non-ibus method (KDE Settings->Input device-> Layout-> add English and other
keyboard, select Main shortcut to change language) is used, input is working
with lokalize without issue.

Reproducible: Always

Steps to Reproduce:
1.Run lokalize app (install if it is not installed - dnf install lokalize)
2. open any translation (po) file
3. use Page Up and Page Down  OR
4. Try type anything, when ibus is active (Settings->Input Device->Virtual
Keyboard->Select ibus)
5. Switch to non-English layout (I used Punjabi)
6. Switch to different application window (Alt +Tab)
7. Alt + Tab - back to localize

Actual Results:  
for 3: There is no change in translation line (Next with Page Up, Back with
Page Down)
for 4. Not text input is shown with any character, space

after Switch back to Lokalize (with Alt+Tab)
- Text will be updated

Expected Results:  
for 3: Page Up and Page down should work to move to next or back line
for 4: Translation text should be updated with typing

- ibus is working normal for kate, kedit and firefox within KDE environment

There is bug in KDE upstream, but not sure how relevant with this:
