Describe the bug

If the query options include the following:

throwOnError: () => false,  
retryOnMount: true,  
staleTime: Infinity,

then on remount of the host component, queryFn is not called, even though the documentation suggests otherwise.

Your minimal, reproducible example

https://stackblitz.com/edit/react-93scwtvo

Steps to reproduce

1. Wait for the app to load and open the console.
2. Click the "Open Modal" button — you will see "Fetching..." messages in the console indicating data fetch attempts.
3. Click the "Close Modal" button.
4. Click "Open Modal" again — no more "Fetching..." messages appear.

Expected behavior

I expect that if a Query is in the error status and I set retryOnMount: true in the options, then when the function passed to throwOnError returns false, the Query should still call queryFn on remount of the host component.
