Start in src/extensions/DropCursor/multiColumnHandleDropPlugin.ts, where the drop handler removes the dragged block and then rewrites the column structure in separate editor calls. Check how editor.transact() groups steps for undo, and look for an existing test covering multi-column drops to extend. Done when one undo after a drop restores the original document with the block visible.

What’s broken?

When I drag a block to the left or right of another block to create a multi-column layout, undoing the move once makes the moved block disappear from the document. Undoing a second time restores the block to its original position.

What did you expect to happen?

A single undo should revert the entire drag-and-drop operation and restore the document to its original state, with the moved block visible in its original position.

Steps to reproduce
  1. Create a document with at least two blocks.
  2. Use a block's drag handle to move it to the left or right of another block, creating a multi-column layout.
  3. Trigger Undo once (for example, by clicking the editor's Undo button or calling editor.undo()).
  4. Observe that the moved block disappears.
  5. Trigger Undo again and observe that the block returns to its original position.

Chrome on macOS; exact browser version not recorded.

Additional context

In src/extensions/DropCursor/multiColumnHandleDropPlugin.ts, the drop handler removes the dragged block and then updates or replaces the column structure using separate editor operations. This appears to split a single drag-and-drop action into multiple undo-history steps. In a local patch, wrapping the removal and column update/replacement in editor.transact() made one undo restore the original document.
