Contribution guidelines

• I've read the contribution guidelines and wholeheartedly agree

I've found a bug and checked that ...

• ... the problem doesn't occur with the mkdocs or readthedocs themes
• ... the problem persists when all overrides are removed, i.e. custom_dir, extra_javascript and extra_css
• ... the documentation does not mention anything about my problem
• ... there are no open or closed issues that are related to my problem

Description

I've noticed that my code annotations only appear with their numbering on the printed output on Firefox 93.0 and Chrome 94 when using the example provided in the documentation.

Expected behaviour

Code annotations should be fully visible and printed below a code block.

Actual behaviour

Only the list numbers are visible below a code block.

Steps to reproduce

1. Create a new mkdocs project mkdocs new ..
2. Use the configuration posted below.
3. Edit the index.md:

   # Welcome to MkDocs
   
   For full documentation visit [mkdocs.org](https://www.mkdocs.org).
   
   ## Testing
   
   ``` js
   document$.subscribe(function() { // (1)
     var tables = document.querySelectorAll(/* (2) */ "article table")
     tables.forEach(function(table) {
       new Tablesort(table)
     })
   })
   ```
   
   1. Annotation 1
   2. Annotation 2

4. Build documentation and print index.html

P.S. Workaround seems to be a new-line between the list elements:

# Welcome to MkDocs

For full documentation visit [mkdocs.org](https://www.mkdocs.org).

## Testing

``` js
document$.subscribe(function() { // (1)
  var tables = document.querySelectorAll(/* (2) */ "article table")
  tables.forEach(function(table) {
    new Tablesort(table)
  })
})
```

1. Annotation 1

2. Annotation 2

Good catch, definitely a bug. I'm currently in the process of fixing all issues reported for code annotations. I'll revisit this issue as part of this undertaking, which will also fix all alignment and positioning issues in #2475.

Temporary workaround: as you already realized, putting a newline between annotations temporarily fixes the issue.

Fixed in 8b11bfb.

[lampensau]

I can confirm. Annotations are now printed correctly.
