[LVGL] Keyboard events are scrambled in LVGL v9

[fietser28]

Describe the bug
The keyboard widget in v9 doesn't send a READY event, only a cancel event when READY is pressed. Cancel doesn't create an event.

To Reproduce
Steps to reproduce the behavior:
Run the attached project in simulator in debug mode.
Press the OK button: a cancel even is generated.
Press the cancel button: no event is generated.

Expected behavior
Same as in v8.3

** LVGL version (if used)**
V9 is not working. Changing the project to v8.3 it works.
