Accessibility when setting alarm with tab key and keyboard only

[jerome-rdlv]

Hi, I just wanted to report an issue with keyboard usage : when I try to configure an alarm using only tab key to move from field to field, the focus goes through all the Repeat panel fields, even when this panel is closed, and so no focus is visible until it finally goes out of this panel, which is confusing. I think only the panel toggle should receive focus when the panel is closed. Thanks for the great app anyway.
