This is confusing because Duo won't have sufficient context or guidance to provide any meaningful suggestion. ### Steps to reproduce In VS Code: 1. Enter a single space or single tab 2. Create new file 3. Observe code generation suggestion I was unable to reproduce this in the web IDE. I haven't tested additional IDE's outside of VS Code. ### What is the current _bug_ behavior? Duo provides a code generation suggestion without sufficient context to provide anything helpful or useful. I believe it's invoking code generation based on the `The file you’re editing has fewer than five lines of code.` logic \[https://docs.gitlab.com/ee/user/project/repository/code_suggestions/#code-generation\\\]. ### What is the expected _correct_ behavior? In an empty file, there shouldn't be a suggested generation or completion when the user enters a single space or single tab. ### Relevant logs and/or screenshots **Repro 1**  **Repro 2** https://gitlab.com/gitlab-org/gitlab/-/issues/503351#note_2216391564  ### <!--If you don't have /label privileges, follow up with an issue comment of `@gitlab-bot label ~"type::bug"`-->
