[CCSM] Can't change keyboard focus to the right-hand side
Filter input in the left-hadn side is always focused, and it's impossible to enter anything in right-hand side string inputs

CCSM Version 0.9.13.1

Steps to reproduce
1. Run ccsm
2. Enter 'deco' in filter input in the left-hand side
3. Click 'Window decorations' plugin button
4. Click 'Command' string input field
5. Type anything with the keyboard

Expected result: 'Command' input field is changed
Actual result: All you type goes to 'Filter' input

I cannot reproduce this with ccsm 0.9.14.1. Probably it was fixed when we switched from GTK 2 to GTK 3.

Still reproducible on 0.9.14.1
