drag-and-drop

Describe the bug

When using the Swap plugin, it's impossible to cancel a swap once the swap threshold has been met for an item. You can't drag the item back to its original place to prevent a swap. This happens with or without the revertOnSpill: true option.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://sortablejs.github.io/Sortable/#swap
2. Drag "Item 1" to h

• User case:
  • for programmers new to the library to get some context on how to add customization functions and styles
• Implementation ideas:
  • Thinking of creating a markdown doc or webpage or something

Describe the bug
When using move to lower the position of an element, adding 1 to the index does not work, and 2 needs to be added.

To Reproduce
I implemented the following code to move the element position up and down under the ROOT, but the onDown function did not move the element down.

  const {
    actions: { move, delete: deleteNode },
    query,
  } = useEditor();
