Reproduction steps

Screen.Recording.2025-12-31.at.11.58.39.AM.mov

1. Start the Ruby LSP with VS Code or Cursor
2. Open a Ruby file with the sample code below
3. Observe that completion works for the first constant, but not the second.

Note: I can reproduce in VS Code and Cursor, but not Zed, so I suspect it's a bug in the extension.
