[data grid] Footer aggregation not showing with initialState with sortModel and pinnedColumns

[genepaul]

Steps to reproduce

Steps:

1. Open this link to live example: (required) https://stackblitz.com/edit/qwdsn7dq?file=src%2FDemo.tsx
2. Notice that the aggregation isn't showing in the footer
3. Comment out either sorting or pinnedColumns in the initialState and refresh the preview
4. Notice that the aggregation now shows.

Current behavior

This appears to have been introduced in 8.19.0, as I had 8.18.0 and started seeing this issue after upgrading. I had made no changes to my code and this started occurring. As noted in the reproduction steps above, the current behavior is that it is not showing an aggregation value in the footer when both sorting and pinnedColumns are passed in initialState.

Expected behavior

I would expect to be able to pass any combination of values to initialState and still see aggregation.

I can reproduce the issue. It seems like a regression introduced in #19892
