isLoading is not changing to true when placeholderData: keepPreviousData is set

[nodirbekprogrammer]

Describe the bug

This is happening with MUI DataGrid pagination. If I set isFetching for the loading state of the table, as shown in the docs, it keeps loading even when I go back, even if the data is already in the cache, which is very annoying.

Your minimal, reproducible example

I'm not lying

Steps to reproduce

Even with placeholderData: keepPreviousData set, isLoading should work as usual.

Expected behavior

I want to load table only when fetching fresh data.

How often does this bug happen?

Every time

you want to use isPending.

The example uses isLoading for a background loading indicator that is displayed alongside data, not a hard loading state.
