Support MarkdownClientCapabilities

[isovector]

I'd like to be able to inspect the MarkdownClientCapabilities object in LSP 3.16

I've got a PR up for this, but I don't know if it will necessarily help you. I don't think clients are obliged to send this if they support markdown, e.g. I know that lsp-mode doesn't.

Ah, I suspect what you actually want is this: https://microsoft.github.io/language-server-protocol/specifications/specification-3-17/#hoverClientCapabilities

(Which is already supported!)
