dragDisabled not immediately updating when using $state rune #642
Description
After upgrading from Svelte 4 to 5 I've found an issue where when implementing dragDisabled with a custom drag handle, the property is not updating immediately and requires an extra mouse click.
See playground for reproduction. When the mousedown event fires the item should be immediately draggable but it's not draggable until a second click and drag. I'm not using the draghandlezone wrapper action since I need access to when the item becomes draggable.
