VS Code: slash command arguments cannot be added when selecting from the command list

When selecting a slash command (e.g. /Notion:find) from the autocomplete list in the VS Code extension, the command is submitted immediately with no opportunity to append arguments.

Expected behavior: After selecting a slash command from the list, the input field should remain active with the command text inserted, allowing the user to type arguments before submitting.

Workaround: Manually type the full command + arguments (e.g. /Notion:find grooming) instead of using the autocomplete list.

Environment:

• VS Code extension
• OS: Linux
