android - Android ConstraintLayout app:layout_constraintDimensionRatio 问题

Question

【环境】
Android Studio 4.2.2
gradle 6.7.1

[build.gradle(app)]
实施 'com.google.android.material:material:1.3.0'
实施 'androidx.constraintlayout:constraintlayout:2.0.4'

[问题]
app:layout_constrainDimensionRatio，在 1 到 2 周前可以正常工作，现在无法正常工作
我最近将 Android Studio 更新到 4.2.2 但我不确定是否是这个原因

        </androidx.constraintlayout.widget.ConstraintLayout>

    </LinearLayout>

    <TextView
        android:id="@+id/tv_text"
        android:layout_width="0dp"
        android:layout_height="50dp"
        android:layout_marginStart="16dp"
        android:text="text-text"
        app:layout_constraintBottom_toBottomOf="@+id/iv_chat_channel"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toEndOf="@+id/iv_chat_channel"
        app:layout_constraintTop_toTopOf="@+id/iv_chat_channel"/>

</androidx.constraintlayout.widget.ConstraintLayout>

结果 iv_chat_channel 宽度为 0dp

但是，将下面的代码添加到 iv_chat_channel 工作正常

app:layout_constraintEnd_toStartOf="@+id/tv_text"

或将 cl_container 的高度设置为 match_parent 并且比率将起作用

最近发生了哪些变化？
