Restoring pinned data from BlockstoreIDB

Hey everyone,

I'm having issues restoring the stored data using BlockstoreIDB.
When creating my node I'm initializing the Blockstore like so:

```
let localSafedBlockstore = window.localStorage.getItem("blockstore");

if (!localSafedBlockstore) {
localSafedBlockstore = "blockstore-" + window.crypto.randomUUID();
window.localStorage.setItem("blockstore", localSafedBlockstore);
}

const blockstore = new IDBBlockstore(localSafedBlockstore);
await blockstore.open();
```

When I look into the IndexedDB in my Browser, everything is created as expected using `helia.pins.add(cid)`.
However, when i restart my node, the contents of IDB is not pinned again so others nodes do not know about it.
Do I have to repin the data again when restarting the node? Or do I have to intialize the blockstore in a special way when restarting the node?

EDIT: I tried to repin the data when restarting the node but it doesn't change anything.
```
for await (const item of helia.blockstore.getAll()) {
const cid = await fs.addBytes(item.block);
helia.pins.add(cid);
}
```
