Inline code in header looks weird #2218
Description
## The `File` modulerenders as https://hexdocs.pm/elixir/1.19.4/io-and-the-file-system.html#the-file-module
It should have the same size as the rest of the test in the header.
This looks confusing when the header starts with the code part, and even worse when the whole header is code (you cannot distinguish it as a header).
