VSCode does not honor LSP-advertised capabilities when displaying inlay hints menu

[awelc]

Type: Bug

I am developing an LSP server for a new language (Move). As you can see here the server advertises only the following capabilities:

• hover_provider
• completion_provider
• definition_provider
• type_definition_provider
• references_provider
• document_symbol_provider
• inlay_hint_provider

In particular, it does NOT provide:

• implementation_provider
• declaration_provider

This is honored by VSCode when displaying the Ctrl-mouseclick menu on an identifier in the code (in this case it's a name of a struct being defined):

However, it is not honored in the menu created when the location field of the InlayHintLabelPart structure is set to the location of the same identifier (notice that the menu includes Go to Declaration and Go to Implementations)
