Summary

Reproduction Steps

Here is a reproduction steps:

open a Rust source code file and write:
```
fn main() {}
```

/// /// # H1 /// /// ## H2 /// /// ### H3 /// /// bold text /// /// italicized text /// /// > blockquote /// /// 1. First item /// 2. Second item /// 3. Third item /// /// - First item /// - Second item /// - Third item /// /// code /// /// --- /// /// title /// /// alt text fn foo() {}

/// | Syntax | Description | /// | --------- | ----------- | /// | Header | Title | /// | Paragraph | Text | /// /// /// { /// "firstName": "John", /// "lastName": "Smith", /// "age": 25 /// } /// /// /// Here's a sentence with a footnote. [^1] /// /// [^1]: This is the footnote. /// /// ### My Great Heading {#custom-id} /// /// term /// : definition /// /// ~~The world is flat.~~ /// /// - [x] Write the press release /// - [ ] Update the website /// - [ ] Contact the media /// /// That is so funny! :joy: /// /// I need to highlight these ==very important words==. /// /// H~2~O /// /// X^2^ fn bar() {}


2. ensure the lsp is running
3. move to the `foo` in line 68, and press space bar then the key `k`
4. the popup will looks like:
