Searching in timeline event notes is barely usable because it loses focus

1. Record some events in the QML Profiler.
2. Select an event.
3. Add a note to the event, e.g. "My note".
4. Select a different event.
5. Click "Search timeline event notes."
6. In the search bar, type the first character of the note from step 3, e.g. "M".
   The note is being found, its location is show in the code editor and the editor gets keyboard focus.
7. Type the second character of the note from step 3, e.g. "y".
   This will go to the code editor.

This way, searching for a note requires typing each single character and always giving back focus to the search bar in between. This is barely usable. Instead, the search bar should keep keyboard focus all the time.
