We have a problem with how the outline behaves after an extension host restart.

1. Have a file open that generates an outline, such as an .R file or a .qmd file with either R or Python code; note the outline
2. Run Developer: Restart Extension Host
3. Note that although a lot comes back online after the restart (your console contents, Variables, Plots), the outline is now gone
4. Try clicking to a different file and back; note that this isn't enough to get the outline back
5. Run Developer: Reload Window; note that this does get the outline back

This does not happen for every kind of file. For example, the outline comes back for regular .py files.
