The keyboard is unable to send control modifier

[vojtapl]

The buttons Undo/Redo/... in selection mode do not work for me (tested on Nix-unstable and Manjaro with KDE Plasma 6.1.4). The key modifier are not sent, only the Copy key sends something, but the text is not copied to clipboard. Here is what I get: maliit.webm

When I dug a bit deeper into it, calling sendKeyPressAndReleaseEvents(Qt::Key_C, Qt::ControlModifier); only send a C, so this may be a problem with the framework and not the keyboard.
