Description in Object Properties is not stored
#### Steps to reproduce:
<!-- Describe what you did (step-by-step) so we can reproduce: -->
- open Inkscape
- draw a rectangle
- open the Layer and Objects dock
- right click on the rectangle (that is drawn on layer 1)
- select "Object properties"
- enter values for ID, Label, Title, Highlight Color (press "Enter") after submitting every value
- type some content in the Description field.
- click somewhere else than on the rectangle to deselect it
- click on the rectangle to reselect it
#### What happened?
- ID, label, title and highlight color are all stored
- the content of the "Description field" is not stored
- other fields store their value upon leaving the field
- after pressing the "Set" button, the description seems stored.
#### What should have happened?
- when removing focus from the description field, the content of this value should be stored (like the other object properties)
- if it is not desirable (for whatever reason) to autosave this content...
1) a warning should appear that you are about to loose date and
2) the "Set" button should appear closer related to this field and be more prominent.
