When we enabled TwoSlash, it injected some elements to provide the type information inline. It works great until you copy the code (you can try on https://shikiji.netlify.app/packages/twoslash).
I didn't find a good and agnostic way to opt-out elements from being printed in
.textContent,so I guess actually removing those elements before grabbing the content might be a more solid idea.I picked a kinda natural selector,
.vp-copy-ignore, so in Shikiji integration, I could provide an option for users to inset that class. On another pov, I am not sure how much VitePress would be interested in document the usage of twoslash or even ship it as a feature.
