changing a `$state` value inside a drag event fires the event twice

[ssebastianoo]

Describe the bug

When inside a drag event, like dragenter or dravleave, changing a $state value will fire the event again

Reproduction

let dropping = $state(false);

onMount(() => {
  window.addEventListener('dragenter', (e) => {
	  e.preventDefault();
	  console.log('dragenter fired');
	  dropping = true; // this re-runs the event
  });
...

What happens if you use svelte:window

Please provide a reproduction in the form of a REPL link or github repository

I cannot manage to reproduce it in other apps but svelte:window fixed it, I guess it was something related to how I was handling the states.
