Why after adding reselect the component is still updated when the old data arrives?

Question

React

My code: https://codesandbox.io/s/n15060lny4

When I click on noop, I add the same data but with a new link to the object, since the data is the same, the link should return the old one from the memoization of the reselect, and accordingly there should not be an update , but for some reason the component is updated exactly.
Simple example:

const selectData = createSelector(
  data => data,
  data => [...data]
)

// Должно быть true но возвращает false
console.log(selectData([{a:1}, {a:2}]) === selectData([{a:1}, {a:2}]))

This is the standard behavior of the library. By default, an identity check is performed:

function defaultEqualityCheck(a, b) {
  return a === b
}

The library API provides the ability to create a selector builder with custom comparison.
The official documentation has an example with deepEqual
