           Summary: Apps launched from calc key breaks num lock/number pad
                    use

SUMMARY
When I launch apps from my Calculator key (keycode 148, keysym 0x1008ff1d,
XF86Calculator), they either don't  run or behave as if Num Lock is off

STEPS TO REPRODUCE
1. Use keyboard with a Calculator key
2. Go to System Settings > Shortcuts and assign that key to launch an app (I
used KCalc), it should show as "Launch (1)"
3. Ensure Num Lock is on
4. Press the Calc key

OBSERVED RESULT
Depends on app, will not launch, or launches but does not accept numeric keys,
e.g. `.` behaves as Del.

EXPECTED RESULT
Normal launch, numeric keys produce input.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Kubuntu
KDE Plasma Version: 5.27.4
KDE Frameworks Version: 5.104.0
Qt Version: 5.15.8

ADDITIONAL INFORMATION
I normally have that button assigned to launch KCalc. I have Num Lock on all
the time, including at boot, and haven't noticed any problems with other apps
respecting number pad keys/num lock, generally.

It occurs only from that type of launch; if I set and use a different shortcut,
e.g. the Pause key or Ctrl + Alt + K, or launch it from KRunner or the main
apps menu, it's fine. If I switch to another app and back, or toggle Num Lock
off and on, the app respects Num Lock again.

I tested by assigning the Calc button to launch KCharSelect. It assigns okay,
but won't launch the app. The same occurs if I set it to launch Kate. Assigning
it to launch Emoji Selector produces similar behaviour to Kcalc, e.g. 2, 4, 6,
& 8 move the selection highlight the same way dedicated arrow keys do.

I wonder if it's somehow related to bug 433645, though I am able to assign
shortcuts with it.
