Comece reproduzindo a falha de navegação pelo teclado no GitHub Copilot CLI 1.0.68 enquanto estiver desconectado, usando a tecla de seta para a direita na aba Session. Rastreie o ponto de entrada da navegação entre abas e verifique se a aba Gists é aberta com a tecla de seta, enquanto a navegação pelo mouse e a navegação reversa continuam funcionando.
