The OK button has the O accelerator and Alt-O highlights the button, but does not press it. Using Ctrl-Return works fine.
Seems to be a kirigami design issue. The MnemonicAttached class does not/can not check whether an accelerator is already used by the QWidget world, which results in duplicates. In this case it's either "P&ositioning" or "&Order" as duplicate.
I think i'll try to detect if we are in a QQuickWidget. in this case i'll disable completely the automatic computation of shortcuts
