filename dropdown disappear too soon

### Checks

- [x] I have searched [github.com/aws/amazon-q-developer-cli/issues](https://github.com/aws/amazon-q-developer-cli/issues?q=) and there are no duplicates of my issue
- [x] I have run `q doctor` in the affected terminal session
- [x] I have run `q restart` and replicated the issue again

### Operating system

macOS 26.1.0 (25B78)

### Expected behaviour

While autocomplete dropdown appears, it should last till I can use up/down arrow to pick one option

### Actual behaviour

In a folder where there are many python scripts whose names strat with `check`, when I type `./check`, the files listed as a dropdown but disappears in too short a period for me to use up/down arrow to pick one to execute.

Es ist keine Quelldatei und kein Test angegeben. Beginne damit, das Autocomplete-Verhalten unter macOS 26.1.0 mit zsh und Version 1.21.0 zu reproduzieren, indem du ein Verzeichnis mit vielen Python-Skripten verwendest, die mit `check` beginnen; bestätige, ob das Dropdown verschwindet, bevor eine Auswahl mit den Pfeiltasten getroffen wird. Erledigt ist es, wenn die Dateinamenvorschläge lange genug verfügbar bleiben, um mit den Pfeilen nach oben/unten eine Option auszuwählen.
