"Recent" Group do not appear when opening the "Select by expression" dialog

[Antoviscomi]

Hi all,
I noticed abnormal behavior in the "Recent" Group of Select by Expression Box
this group it's now disabled by default in tree and it appears only in case of user write a new query expression and make a selection, as follow:

• the user write the expression ---> the group Appears;
• the user close "Select by expression box" ---> the Group disappears;
  Furthermore, when the Group It's Active the last expression writed it appears stored in recent for a lot of times.
  I attach a screencast of this behaviour (.AVI in a zipped file)
  recentinselectbyexpression.zip

this affect stable and master versions

The Recent group is not visible when the Select by expression dialog opens (Ctrl + F3),
so I confirm only in part and only for the master.

Hi @pigreco ,
if you make a new query with the same expression this expression will stored again in recent...
as you can see in screencast that I have attached

@Antoviscomi this seems to be a separate issue, please file a separate ticket.
