I've been trying to mimick the files.autoReveal behavior of the regular explorer in the Dependency Explorer of the Haxe extension. I can expand the necessary nodes just fine, but I don't think there's any way to scroll to the correct position in the view + highlight the node programmatically right now.

From what I can tell, the currently planned enhancements won't help with this (#27823). Could a function for selecting a node be added to API? I think a lot of other extensions would benefit from this as well, Code Outline comes to mind.
