Bug with links

I'm trying to dynamically render new links with this code:

```
const renderLoop = setInterval(() => {
renderer.pause();

setTimeout(() => {
// Render new transactions
for (let i = 0; i < batch; i++) {
const transaction = getTransaction()
addLink(transaction.sender, transaction.recipient);
if (currentTransaction < TRANSACTIONS.length) {
nextTransaction()
} else {
clearInterval(renderLoop)
return;
}
}
renderer.resume();
}, 0)

}, 2000)
```

And after a couple renders there appear a "ghost" links not connected to any node and with static positioning (they not animated like other nodes)

Please, help me to figure out why it can happens?

Use the provided render loop as the reproduction case, tracing renderer.pause(), renderer.resume(), addLink(), and nextTransaction() first. Confirm why links become disconnected and statically positioned after repeated renders; done means the cause is identified and the rendering behavior is corrected without ghost links.
