Why the vertical height of the table does not expand beyond approximately 600px

[owolfdev]

I am working with the expandable table example here:

https://codesandbox.io/p/sandbox/tanstack-table-example-expanding-jr4nn3

Works great until the table contents size in y is bigger than about 600px

Here is my implementation:

https://collapsible-tree-view-in-react.vercel.app/expandable-data-table-test
https://github.com/owolfdev/Collapsible-Tree-View-in-React/tree/main/app/shcn-table-with-notion-data

Any help in finding where to adjust this so the table can expand beyond the current limit?
