Tab completion for slash commands doesn't move cursor to end of completed text

[mkusaka]

What version of Codex is running?

codex-cli 0.22.0

Which model were you using?

gpt-5

What platform is your computer?

Darwin 24.6.0 arm64 arm

What steps can reproduce the bug?

1. Start codex
2. Type /c (cursor is right after the 'c')
3. Press Tab key to complete to /compact (which appears as the filtered candidate)
4. The text /compact is inserted, but the cursor remains at position 2 (after /c) instead of moving to the end of the completed text

What is the expected behavior?

When tab completion inserts /compact, the cursor should move to the end of the completed text (position 8, after /compact).

What do you see instead?

The text /compact is correctly inserted, but the cursor stays at position 2 (after /c), making it difficult to continue typing. Users need to manually move the cursor to the end to continue input.
