SUMMARY

Layout switching set to Alt+Shift breaks Alt+Shift+Tab shortcut for reverse navigation through windows.

STEPS TO REPRODUCE
1. Set the Reverse Navigation Through Windows shortcut to Alt+Shift+Tab
2. Select Alt+Shift as a Switching to another layout shortcut
3. Open multiple windows
4. Press Alt+Shift+Tab

OBSERVED RESULT
1. If the forward navigation through windows set to Alt+Tab: Alt+Shift+Tab firstly switches the layout right after the combination Alt+Shift is pressed then after the Tab pressed and released(while Alt and Shift are held pressed) KWin switches windows in a forward direction.
2. If the forward navigation through windows is assigned to other combination, e.g. Alt+F12: Alt+Shift+Tab only switches the layout right after Alt+Shift is pressed.

EXPECTED RESULT
Switching layouts by Alt+Shift and switching windows backwardly.

SOFTWARE VERSIONS
(available in About System)
KDE Plasma Version: 5.13.5
KDE Frameworks Version: 5.50.0
Qt Version: 5.11.2

ADDITIONAL INFORMATION
Probably changing an event type for layout switching from "key pressed" to "key released" could solve the problem.
