public void requestLayout() {
    super.requestLayout();
    // We need to intercept this method because if we don't our children will never update
    // Check https://stackoverflow.com/questions/49371866/recyclerview-wont-update-child-until-i-scroll
    if (!mRequestedLayout) {
        mRequestedLayout = true;
        this.post(() -> {
            mRequestedLayout = false;
            layout(getLeft(), getTop(), getRight(), getBottom());
            onLayout(false, getLeft(), getTop(), getRight(), getBottom());
        });
    }
}

while still, I would have preferred this to fixed after 4, 5 years, however, this was a good workaround, and you won't forget about them in your view.
