Search running showing random overlapping entries as well as search results

SUMMARY
Searching for entries in the System Tray Settings applet causes correct results to show, but there are some entries that don't match the search, displayed in the same results area, which means both matching matching entries and non-matching entries are written over one another.

STEPS TO REPRODUCE
1. Right-click "Show hidden icons" and select "Configure System Tray"
2. Select tab "Entries" in the settings applet
3. Search for anything with at least one matching result ("x" or "j" return no results, for me, and don't cause the issue)

OBSERVED RESULT
Usually there will be random other entries somewhere below the matching result. They are displayed in the same position in the search as were they were in the main list of entries, prior to starting the search. After the non-matching results first display, they will remain visible until the applet is closed or until you switch tabs in the applet. The expected entries are written on top of the non-matching entries, including (when you stop searching) the same entry itself, which is displayed at the same position twice (You can see the text is written to the area twice, for example).

EXPECTED RESULT
Only matching entries shown in search results, stop searching and entries to display are properly cleaned up.
