[VirtualizedList] Resize listener not properly working if dimensions decrease

[Dudrie]

If the webpage is made smaller (in height or width) the ResizeObserver on the list's root div is not fired properly (ie at all). This leaves to more and unnecessary scrollbars on the page.

✔️ Expected behaviour

Making the window smaller should result in the VirtualizedList's size being properly adapted.

⚡ Actual behaviour

Making the window smaller does not change the size of the VirtualizedList.

🕹️ Steps to reproduce

1. Open page with VirutalizedList.
2. Make the window smaller.
3. Observe that the size of the VirtualizedList was not properly adjusted.
