Remove non effective CSS for CM6 search panel input

[spacegaier]

Breaking change

Proposed change

Code line has no effect. I tried to set the label CSS class to use font-size "100%" for the "match case" checkbox, but could not get it to work and realized that the statement for input also has no effect.
