Outline is always collapsed to the namespace level with clangd

I have a test project using multiple namespaces and clangd for indexing. The Outline view is supposed to be synced with the editor, but it's always collapsed to the namespace level, and I need to manually expand it every time to see which function the cursor is at (see Outline.png).

Also missing is the alphabetical (as well as other) method of sorting in the Outline view, which currently exists with the clang code model but not for clangd. I have attached a minimal example project.
