You should avoid map/filter operations for returned values from mapSelect. They will always return new reference and force component to re-render even if derived value is the same.

P.S. You should see warning in console for similar cases in dev mode. See #53666.

Thanks for the info! I wasn't aware of that 🙂 I have just changed it in this commit.

Not related to this pull request, but do you think it could be an issue also here? I'm happy to create another PR to change that.

Thank you, @SantosGuillamot!

That one is okay. It will pass a shallow equality check since the filteredPostTypes values will have the same reference. It's somewhat undocumented and a last-resort hack.

It usually depends on the case; check for a warning in the DevTools if you're unsure.

// ❌ will fail shallow equality since the `postType` property has a new reference on each call.
return {
   postTypes: types.filter( () => /*--/* );
}

// ✅ will pass shallow equality since returned object properties have the same object reference
return types.filter( () => /*--/* );

};
