GUI: "Jobs view" -> menu "View" disappears

The bug was found during the consulting Ya-Ru. From my memory (details can be inexact):

• brew-installed BornAgain v23 on MacBook Pro M4
• simulate with data -> menu "View" exists in Jobs
• try to click "View" -> "Fitting activity"
• menu disappears, activity is not applied
• menu does not appear back
• BA GUI cannot be used for fitting
