Closes https://github.com/zed-industries/zed/issues/42356 This PR fixes the history view losing focus by simply always displaying the search editor. I don't think it's too weird to not have it when it's empty, and it also ends up matching how regular pickers work. Release Notes: - agent: Fixed a bug where navigating the agent panel with the keyboard wouldn't work if you visited the history view and it was empty/had no entries.
