`(DNS) Filter Editor` — Set the focus adequately after certain actions, like deleting a rule (for use of the up/down arrow keys)

[contribucious]

(:wave:) Steps to reproduce

 

1. Right-click on the AdGuard systray icon > Tools > (DNS) Filter editor.  

2. Open the advanced filter editor and add the following rules then save:

||example.org^
||example.com^
||example.net^

:eyes: Problem n°1 now encountered: Observe that you can't use your up/down arrow keys to navigate between them.  

3. Using your mouse therefore, select the first one (||example.org^) then after observing that your up/down arrow keys now work, delete it (via the DEL key or via the adequate bottom icon '—'). The second one (||example.com^) now becomes selected.  

:eye_speech_bubble: Problem n°2 now encountered: Observe that you can't use your up/down arrow keys to select the next one (||example.net^).
