Android A11Y TalkBack: Text Items not usable

Context

Text on Android Phone with TalkBack activated should be shown as dedicated elements a blind person can navigate through. It has to fulfill requirements of WCAG 2.0 / WCAG2ICT

Expectations

• Each Text Item should have it's own visible focus Rectangle
• User can navigate through the text blocks

A good example from a blind person on youtube using the TalkBack feature with text in an app: https://youtu.be/YJSWYLZD8EI?t=179

Observation

All texts are read as once. Focus Rect is full application window. No difference between StaticText and Heading.

The following sample is reading: "A11YWorld, A11YHeading". 

 Code

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

Window {
    visible: true

    Column {
        spacing: 16

        Text {
            text: "Hello"
        }

        Text {
            text: "World"
            Accessible.role: Accessible.StaticText
            Accessible.name: "A11YWorld"
            Accessible.description: "A11YDescription"
        }

        Text {
            text: "Heading"
            Accessible.role: Accessible.Heading
            Accessible.name: "A11YHeading"
            Accessible.description: "A11YHeading"
        }

    }
}

 Output

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