Android A11Y TalkBack: Button click AND pressAction are called

Update by Reporter: Looks like this issue was fixed with 5.15.3. Reporter CI/CD environment built a version with 5.15.2 which still had the issue.

Context

QtQuick Controls 2 Button on Android Phone with TalkBack activated to fulfill requirements of WCAG 2.0 / WCAG2ICT

Expectations

• A button should call "onClicked" only on touch without TalkBack is off.
• A button should call "Accessible.onPressAction" only if TalkBack is on

Observation

Clicking on the button calls both functions.
If the code is for example a toggle logic like "variable = !variable" this could not work.

 Code

import QtQuick 2.15
import QtQuick.Controls 2.15
import QtQuick.Window 2.15

Window {
    visible: true

    Button {
        text: "Button"
        onClicked: () => { console.log("onClicked"); }
        Accessible.name: text
        Accessible.onPressAction: () => { console.log("onPressAction"); }
    }
}

 Output

Output after opening the app, focus button and "click" on it via Android TalkBack.
