SUMMARY
On Plasma 6.5.2 (Wayland), the Alt+Tab task switcher (“Walk Through Windows”) advances through multiple windows when I press-and-hold Alt+Tab, even when Key Repeat is disabled in System Settings. I expect exactly one step to the previously used window per physical key press, and no repeated cycling while Tab is held.

STEPS TO REPRODUCE
1. System Settings -> Keyboard -> Key Repeat: turn OFF “Key repeat” (Apply).
2. Log out and log back in (Wayland session) to ensure settings are applied.
3. Verify repeat is actually off in a normal text field/app (e.g. in KWrite: press-and-hold the “a” key; it should type only one “a”).
4. Open 3+ application windows.
5. Press and hold Alt, then press and hold Tab (keep Tab held down).

OBSERVED RESULT
The task switcher selection advances through multiple windows while Tab is held, even though key repeat is disabled globally. (In my case it does NOT wrap around endlessly; it stops at the ends.)

EXPECTED RESULT
With Key Repeat disabled, holding Alt+Tab should not generate repeated “Tab” actions in the task switcher. It should move at most one step (to the previously used window) per physical Tab press.
