Documentation comments don't show mathematical formulas in IntelliSense

Bug type: Language Service

As seen in the attached image, VS-Code doesn't display mathematical formulas in C++ documentation comments.

Note that I've inserted some new lines between the doc comments and the function so that you can see them clearly, however this does not affect the issue. It persists when there are no extra new-lines added.

This has been mentioned in this issue, however was marked closed after being determined to somehow be a duplicate of this (seemingly) un-related issue, which was marked as fixed in an older release (1.8.2).

I have tried using various formats to no avail (see the mathematical formula sections of this and this):

• Different types of block comments:
  • ///
  • /** */
• Different formula tags (with and without spaces around the formula):
  • @f[formula@f]
  • \f[formula\f]
  • \f{formula\f}
  • \f$formula\f$
• Inclusion and exclusion of other tags such as @brief, <summary> etc

Additional info:

• OS: Windows 11 Home x64 - Version 21H2 - Build 22000.493
• VS Code Version: 1.65.1
• C/C++ Extension Version: v1.8.4
• Issue persists when cpptools is the only extension installed

c_cpp_properties.json configuration:

{
    "configurations": [
        {
            "name": "Win32",
            "includePath": [
                "${workspaceFolder}/**",
                "${workspaceFolder}/source"
            ],
            "defines": [
                "_DEBUG",
                "UNICODE",
                "_UNICODE",
            ],
            "windowsSdkVersion": "10.0.19041.0",

            "cStandard": "c17",
            "cppStandard": "c++17",

            "forcedInclude": [
            ]
        }
    ],
    "version": 4
}

Start at the IntelliSense rendering of C++ documentation comments and reproduce the issue in VS Code using the supplied c_cpp_properties.json and formula formats. Review linked issues 6136 and 6084 for prior investigation; done means supported mathematical formulas display in the documentation popup. No source file or test is named in the report.
