--------------------------+-----------------------------
 When using the block editor’s List View, dragging a block from one nested
 column to another often results in the block being dropped outside the
 intended container. This disrupts the block hierarchy and can break the
 layout, forcing the user to manually move the block back into place.

 Steps to Reproduce:

 1.Create a new page in the Gutenberg editor.
 2.Add a Columns block with three columns.
 3.Inside the third column, add another Columns block (nested).
 4.Add any block (e.g., Paragraph) inside the nested columns.
 5.Open List View.
 6.Try dragging a block from one nested column to another.

 Expected Result:
 The block should always be placed inside the target column.

 Actual Result:
 The block is often placed outside the intended nested column, sometimes
 even outside the main Columns block entirely.

 Environment:
 WordPress version:  6.8.2
 Gutenberg version: bundled in core
 Theme: Twenty Twenty-Five
 Browser: Chrome 126 (Windows/macOS)
