Persisted store - setItem seemingly over enthusiastic!

[AndrewIsh]

I have a small Zustand store that I am persisting to an external API via getItem & setItem, this is all working great. However, setItem in particular seems a bit "chatty", I'm see maybe 7 calls to my update API where I'd expect 1. During a page load, in DevTools, I'm seeing 7 Actions in my store, 5 of which say (states are equal) in the diff view, this is triggering 7 calls to setItem, which in turn is calling my API 7 times.

I'm wondering if there is a way of making this all a bit more discriminating? In my persist I am using partialize to only persist the single state property I am interested in. I imagined that setItem would only be called when a state update affected that property, but I'm seeing it being called when other state properties are changed. I'm also wondering why it is being called when devtools is telling me an action didn't change the state.

I'm pretty sure I'm misunderstanding this whole thing, so this really isn't a criticism in any way, I'm just wanting to understand what's happening :-)
