match_parent won't work on children of a layout with minHeight

Question

Disclaimer: I'm not able to reproduce this on all devices. I was able to reproduce it on a Galaxy Nexus running 4.2.1 and on a Galaxy Tab A. It doesn't happen on a Nexus 6 running 7.0, though.

Here's a minimum example to explain the situation:

<?xml version="1.0" encoding="utf-8"?>
<ScrollView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fillViewport="true">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <FrameLayout
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:layout_weight="1"
            android:background="#ff0000"
            android:minHeight="500dp">

            <FrameLayout
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:background="#000000" />

        </FrameLayout>

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="some large text here aaaaaaaaaaaaaaaaaaaaaaaaaaa"
            android:textSize="100sp" />

    </LinearLayout>

</ScrollView>

This is a simple layout where I want my parent FrameLayout to take up all the space left by the TextView (that's why I have android:layout_weight="1"). If the TextView leaves a space smaller than the FrameLayout's minHeight, than the content becomes scrollable and the FrameLayout sticks to its minHeight.

Everything works fine while content isn't scrollable, but if the FrameLayout reaches its minHeight and the content becomes scrollable, the child FrameLayout vanishes because its height becomes zero for some reason.

If you look at the Android Studio preview, you'll always be able to see the child FrameLayout, but when you run it (on some devices), you'll only see the parent's background.

The simplest solution is to add the same minHeight to the child FrameLayout, but in my case this isn't a good solution (my child is actually a custom view with some other child views).

Another solution is to force the child height in runtime:

private void ensureChildHeight() {
    parent.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override public void onGlobalLayout() {
            if (parent.getHeight() > 0) {
                parent.getViewTreeObserver().removeOnGlobalLayoutListener(this);

                if (parent.getHeight() == parent.getMinimumHeight()) {
                    child.getLayoutParams().height = parent.getMinimumHeight();
                    child.requestLayout();
                }
            }
        }
    });
}

But that's not great either. Does anyone know what's going on and whether there's a better solution for this? After working on it for some time and from my coworker's feedback, I feel minHeight is just not reliable and I should just avoid it whenever I can.
