In VSCode, outline doesn't show until you edit the file

### Describe the Bug

Simple repro repo: https://github.com/testlabauto/pyrefly_debug

In VsCode, the outline doesn't display unless I start editing the file. Adding a newline is usually enough to get it to start working.

Here is what it looks like upon open of the file:
