#2353 The reason is that VSCode requested document symbols twice for the outline view and the sticky scroll. We cancelled one of them so the outline view shows "no symbols found in document 'A.svelte'". It seems the VSCode ts extension also caches the result from tsserver, mostly because it'll also be used in code lens. But the result is mostly fast enough. A 5000-line file takes like 100ms so we probably don't need it now. We can probably reconsider if #2378 lands and see if there is a large performance regression.

#2130 Porting VSCode's implementation/reference code lens. This is not enabled by default. To enable this, you'll need to enable the
typescript.implementationsCodeLens.enabledconfig or thetypescript.referencesCodeLens.enabledconfig forlang="ts"andjavascript.referencesCodeLens.enabledfor js components. Note that we reuse config for ts/js files so it'll also enable the feature in ts/js files.For non-VSCode users
Due to protocol limitations, this feature only partly works on other LSP clients. A client middleware is required to map reference info to references UI. So LSP client author might need to add support for it. For neovim-lsp users, you'll need a similar solution for the typescript language server.
Screenshots
(Yes. this will work for Svelte 5 props if it's a separate interface)
