When re ordering the children of a Tab widget (i.e. the tabs) any internal ipywidget is hidden. This behaviour does not happen in e.g. Jupyter Notebook.
When clicking on button "switch" it can be seen that the Label "1" and "2" both disappear. This does not happen when doing the same in Jupyter Notebook.
