Binding to store values from multiple components causes multiple updates for same value

[antony]

I didn't know exactly how to describe this one, but it seems like if you bind to a store from more than one component, any manual subscriptions fire more than once for each update.

https://svelte.dev/repl/0a55c906240a46b3807f4135e7ff7c64?version=3.16.4

You will notice in the REPL, that you receive console log messages (or you can look at the "updated" count) to see the problem.

Binding automatically (using $) does not have the same problem.

Updated to latest Svelte. Still an issue it seems.

@antony, Not saying thumbs up because it still happens (lol), I'm trying to mark issues that need attention and see if I can detect it using the API.

Fixed in 3.24.1 - https://svelte.dev/repl/0a55c906240a46b3807f4135e7ff7c64?version=3.24.1

I am at "svelte": "^3.29.7" and this problem still occurs. When i roll back to 3.24.1 the problem is still there too.

In my case I am bound to store 3 times like this:
<CheckboxList bind:array={$filters.foo} />
<CheckboxList bind:array={$filters.bar} />
<CheckboxList bind:array={$filters.baz} />

And manualy subscribed update happens exactly 3 times more, than it should. If I remove this bind, everything works as it should.
