## Slash Command popup issue
#7659
When recalling history, the
composer(`codex_tui::bottom_pane::chat_composer`) restores the previous
prompt text (which may start with `/`) and then calls
`sync_command_popup`. The logic in `sync_command_popup` treats any first
line that starts with `/` and has the caret inside the initial `/name`
token as an active slash command name:
```rust
let is_editing_slash_command_name = if first_line.starts_with('/') && caret_on_first_line {
let token_end = first_line
.char_indices()
.find(|(_, c)| c.is_whitespace())
.map(|(i, _)| i)
.unwrap_or(first_line.len());
cursor <= token_end
} else {
false
};
```
This detection does not distinguish between an actual interactive slash
command being typed and a normal historical prompt that happens to begin
with `/`. As a result, after history recall, the restored prompt like `/
test` is interpreted as an "editing command name" context and the
slash-command popup is (re)activated. Once `active_popup` is
`ActivePopup::Command`, subsequent `Up` key presses are handled by
`handle_key_event_with_slash_popup` instead of
`handle_key_event_without_popup`, so they no longer trigger
`history.navigate_up(...)` and the session prompt history cannot be
scrolled.
