Flow views getting clipped

[enginegl]

I have a horizontal chain flow of programatically added items (key-value pairs).

        <androidx.constraintlayout.helper.widget.Flow
            android:id="@+id/flow"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_marginTop="12dp"
            android:orientation="horizontal"
            app:flow_horizontalAlign="start"
            app:flow_horizontalBias="0"
            app:flow_horizontalGap="8dp"
            app:flow_horizontalStyle="packed"
            app:flow_verticalGap="8dp"
            app:flow_wrapMode="chain"
            app:layout_constraintEnd_toEndOf="@id/endGuideline"
            app:layout_constraintStart_toStartOf="@id/startGuideline"
            app:layout_constraintTop_toBottomOf="@id/title" />

Each item is added with the following layout params:

ConstraintLayout.LayoutParams(
    ConstraintLayout.LayoutParams.WRAP_CONTENT,
    ConstraintLayout.LayoutParams.WRAP_CONTENT
).apply {
    constrainedWidth = true
    constrainedHeight = true
}

When I add an item with a lot of text, the view is being clipped at the bottom (screenshot 1).

Everything is working fine if a flow has no horizontal paddings/margins, and horizontally constrained to the parent (Screenshot 2).

Seems like large views are getting measured wrong.

❌ Screenshot 1 – flow constrained to guidelines (start/end=16dp), large views getting clipped.

✅ Screenshot 2 – flow constrained to the parent, everything is fine.
