Vertical Layout Group width collapses to zero when an empty Horizontal Layout Group child is added and Content Size Fitter uses Preferred Size

Steps to reproduce:

1. Create or open any Unity project
2. Create a Canvas
3. Add a UI Image as a child of the Canvas and remove its Image component
4. Add a Vertical Layout Group component and enable both Control Child Size options
5. Add a Content Size Fitter component and set both Horizontal Fit and Vertical Fit to Preferred Size
6. Add a Text - TextMeshPro object as a child
7. Add another UI Image as a child, remove its Image component, and add a Horizontal Layout Group component
8. Select the parent object and observe the result

Actual result: The parent’s width becomes 0, causing the text to wrap one character per line
Expected result: The parent retains the text’s preferred width, and the text remains on one line
