cubicweb #343981 Preference edition is a bit shaky [deprecated]

The preferences are not always taken correctly into account. For instance:

  • select "visible" on a box and it doesn't appear during the current session
  • select "left", the box appears right, then change it to right, it's still to the right, then change back to left, it's now correctly on the left.
