Describe the bug
When the HTML code is generated from a markdown source any inline code blocks that are part of the title/heading get escaped. Consider the following example:

# Code Guidelines

## 2. Language standard

bla bla

### 2.4. `const` and other modifiers

bla bla

### 12.5. `for` loops
bla bla

### 12.8. `goto`

bla bla

### 12.9. Macros

bla bla

### 12.10. `constexpr`

bla bla

### 12.11. `std::string` vs `std::string_view`

bla bla

This renders as:

It contains two issues:

• Use of <tt> tag which seems to be deprecated (see https://www.w3schools.com/tags/tag_tt.asp), it should probably use <code>
• Text is actually escaped so the browser doesn't render it correctly (from view-source:)

Expected behavior
