Tab key is handled twice on QML

Situation:
Keys.onPressed handler responses twice when Tab key is pressed once.

Source code:
Rectangle {
width: 360
height: 360
TextInput {
anchors.fill: parent
text: "text"
Keys.onPressed:

}
}

Step:
1. Run the above QML Application
2. Click the test so that the caret appears
3. Press Tab key once.

Result:
The following messages are showing on the console

Qml debugging is enabled. Only use this in a safe environment!
Key Pressed 16777217
Key Pressed 16777217

Expected:
"Key Pressed 16777217" should be printed just once.

Thank you.
