Code blocks in triple slash Doxygen comments are formatted incorrectly

Environment

• OS and Version: Windows 11 Enterprise version 10.0.26200
• VS Code Version: 1.127.0
• C/C++ Extension Version: 1.32.2
• If using SSH remote, specify OS of remote machine: N/A

Bug Summary and Steps to Reproduce

Bug Summary:

If you place a Markdown code block inside inside a Doxygen comment that uses /// at the start of each line, and that comment contains any Doxygen tag, and you hover over a symbol to view its documentation, then indentation and // at the start of lines inside the code block is stripped.

The same comment switched to use //! formats correctly.

Steps to reproduce:

Write a function with documentation such as the following:

/// Test function
///
/// Example:
/// ```
/// // This program does the thing.
/// int main() {
///   DoThing();
///   return 0;
/// }
/// ```
/// \param x Test parameter
void DoThing(int x);

Expected behavior:

When hovering over the symbol, the documentation should be rendered as

Test function

Example:

// This program does the thing
int main() {
  DoThing(1);
  return 0;
}

Parameters:
x - Test parameter

Actual behavior:

The documentation renders like this instead

Test function

Example:

 This program does the thing
int main() {
DoThing(1);
return 0;
}

Parameters:
x - Test parameter

Removing the \param line or changing the comment style to //! results in the expected rendering.
