If TextField is located inside Flickable, and you click on the TextField, and then you try to input anything, nothing happens, it keeps being empty.

Example of the code that does not work:

ApplicationWindow {
    id: win
    width: 800
    height: 600
    visible: true
    
    Flickable {
        anchors.fill: parent
        TextField {
            anchors.centerIn: parent
            width: 300
            height: 40
        }
    }
}

It worked in Qt 6.4.2. Looks like this commit broke the Keyboard focus somehow.

One observation. If you click on TextField and press the TAB key once, then the keyboard input will work.
