/* Two things this cell has to do: hold a row of buttons, and stay as tall as
   the rest of its row even when it is empty — the group owner cannot be
   removed, and neither can your own account in the admin table.

   `display: flex` did the second one and broke the first. **A flex <td> stops
   being a table cell**: it no longer stretches to the height of its row, so
   its bottom border is drawn wherever its own content ends. Measured, in a row
   whose other cells were `top 76, height 40`, the actions cell came out
   `top 77, height 30` — its rule nine pixels above the rest, which is the
   staggered lines across the members table.

   So the cell goes back to being a table cell, and an empty one is held open
   by a zero-width strut the height of a button. Reported as "un décalage sur
   les lignes du tableau listant les membres". */
