When the dialog box for Properties->Information is opened we see "add comment" and "add tags". If we choose either one and add a comment or tag it is never saved. However it works correctly if the comment or tag is added from the panel view.

Reproducible: Always

Steps to Reproduce:
1.In Dolphin right click on a file.
2.Choose  properties
3.Choose information
4.Notice links for "add comment" and "add tags"
5.Choose either one
6.Add a comment or tag and click OK
7.Notice that the change appears in the dialog but not the side panel
8.Close and re-open dialog
9.Notice that the change has disappeared
Actual Results:  
The comment or tag that was added never was manifest

Expected Results:  
The change that was made should appear in a subsequent dialog as well as the side panel.

I have noticed this in all the 4.11 series. I am not sure but it may have also been a fault in 4.10.
