Allow user to select only cells
For #8153 (closed) we disabled the user-select in tree and list-form but this prevent user to easily copy/paste content of a cell (which is legit as it is usually user input).
So I propose to allow user-select on cell but also to disallow user-select everywhere else (of course <input/>
are still selectable). Such that CTRL+a
will select all the content of the list.
