useQuery select function is called twice

[TomPradat]

In my application, using version 5.45.0, I get this weird thing where sometimes the select function is called twice.

Here are some takeaways from my debugging session :

1. The select function is defined out of React scope, so it is not the function that changes.
2. When the select is called for the second time, the data argument is the same one (I tested with strict equality ===) as during the previous call.
3. When memoizing the select function, the problem disappears, which supports the previous point.

I've noticed that in https://github.com/TanStack/query/blob/main/packages/query-core/src/queryObserver.ts#L470, the prevResultState.data is undefined when I have the problem, which seems to be the cause of the new call to select.

I tried to reproduce the bug in a codesandbox but unfortunately failed.

Could this be a bug or is there something obvious that I am missing?
