How to reproduce:
In "Contacts" area, open search, type in a word and try starting the search by clicking on the magnifier symbol on the left.
Actual results:
The search cannot be started by clicking on the magnifier symbol (nothing happens when clicking on the magnifier symbol) but must instead be started by hitting Enter.
Expected results:
Since there already is a magnifier symbol the user expects to be able to start the search by clicking on it. Thus, starting the search should be possible by clicking on the magnifier symbol, too (apart from still enabling users to start it by hitting Enter)
