For anyone interested, I just found a solution, I placed #secondList into a table element:

and added the css decorator visibility: visible / collapse

<table>
  <tr>
    <td>
      <secondListComponent></>
    </td>
  </tr>
</table>

according to mozilla:

For rows, columns, column groups, and row groups, the row(s) or column(s) are hidden and the space they would have occupied is removed (as if display: none were applied to the column/row of the table). However, the size of other rows and columns is still calculated as though the cells in the collapsed row(s) or column(s) are present.
