Search bar loses focus while typing

[RodgerLeblanc]

The search bar in the branches panel on the left side sometimes loses focus when typing. It doesn't happen every time, I usually reproduce it easily by following those steps :

1. Select a repository tab in Fork
2. Click inside search bar in the branches panel.
3. Type "12" and wait,
4. Check if focus is lost, if it's not lost, restart at step 1 with another repository tab until focus is lost when typing.
