Qt app doesn't receive Shortcut or Keys.onPressed input when using physical keyboard

Qt application on iOS doesn't react to keyboard input when using physical keyboard.
Please use the attached sample project (Qtbug85727.zip) to reproduce the problem.

E.g.

                Keys.onPressed:
                {
                    if (event.key === Qt.Key_Left)
                    {
                        rect.color = switchColor ? "orange" : "pink"
                        switchColor = !switchColor
                    }
                }

How to reproduce :
Use Qtbug85727.zip .
Press the following keys/buttons to change the color of background
Space key - Switch black and yellow
Left key - Switch orange and pink
Mouse left Button - green
Mouse right button - red

Expected behavior :
The background color changes accordingly.

Actual behavior :
No reaction expect the mouse left button which works.

Typing to TextField works as normal.
