rotation of virtualkeyboard does not work

When I update qt from 5.12.3 to 5.15.0, this issue happens.

I review this issue : https://bugreports.qt.io/browse/QTBUG-83217

The situation is the same.

But I don't know how to modify my qt code ?

Can you give me suggestion?

Thank you very much.

 

My previous code is like this:

Item {
rotation: 90
TextField

{ placeholderText: qsTr("Enter name") anchors.horizontalCenter: parent.horizontalCenter }

InputPanel

{ id: inputPanel y: active ? parent.width - inputPanel.width + 100: parent.width anchors.left: parent.left anchors.right: parent.right }

}
