Net selector filter box has no cursor on GTK

[Thomas Pointhuber]

# Current Behaviour

Entering something in the Net-Selector Filter shows the text, but no cursor. Actually, it shows a different field of the dialogue as selected including a blinking cursor, but the text goes into the correct input field.

It is a little bit annoying because people cannot visually see where cursor inside the field is actually located.

Furthermore: hovering the mouse above the field automatically selects the whole text. This is another unexpected behaviour of the field.

As a side note: when I enter a filter which results in no results, there is a little visual artifact at the bottom of the drop-down list (top of the result widget). Probably it would look a bit nicer when the result list is simply hidden when no results are found.
