### System information

Windows 10

Attempting to reorder the children of a TabContainer results in an unintended ordering and incorrect undo states.

Also happens in v4.0.3.stable.official [5222a99f5].

### Steps to reproduce

1. Add a new TabContainer
2. Add a few children to it
3. Drag and drop to erroneously reorder them
4. Attempt to undo the change
