What
In Claude Code's on-screen interface, some parts are marked as unable to take keyboard focus (with tabIndex set to -1). Trying to focus one of these now sends focus to a part that contains it and can take focus. That is the currently focused part, a recently focused one, or one set to take focus automatically.
Why
Keyboard focus lands on something that can use it instead of on a part that cannot.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
The finding does not say which screens or controls this affects in practice.
