GroupedRowModel is incompatible with Pagination

[smaspe]

TanStack Table version

v8.21.3

Framework/Library version

React v18.2.0

Describe the bug and the steps to reproduce it

When the table is initialized with a pagination state, and the getGroupedRowModel is set, the pageIndex is immediately reset to 0.

Here is a demo https://codesandbox.io/p/devbox/github/tanstack/table/tree/main/examples/react/pagination?embed=1&theme=light

It is taken directly from the pagination example, with 2 changes:

• Updating the initial pageIndex to (for example) 5
• Add getGroupedRowModel: getGroupedRowModel(), to the table options

(Note: this also occurs when a grouping state is passed, but having a grouping state is not required to see the issue)

As far as I can tell the issue is that the _autoResetPageIndex called during the init of getGroupedRowModel is wrapped in a _queue.

As a result the actual call to _autoResetPageIndex occurs after registered has been set to true by other models.
