Intellisense not recognizing constexpr methods of captured values in lambda

Type: LanguageService

Describe the bug

• OS and Version: Windows 10 18362
• VS Code Version: 1.41.1
• C/C++ Extension Version: 0.26.3
• I have CMake tools installed

To Reproduce

1. Write

auto array = std::array<int, 4>{};
array = [&array]{ return std::array<int, array.size()>{}; }();

2. Intellisense will say "Expression must have constant value -- *this cannot be used as constant value"
   (For some reason my Intellisense won't give error messages in English, that error message above is translated from Chinese "表达式必须含有常量值 -- *this 的值不能用作常数")

Expected behavior

This shouldn't be flagged as an error since it's valid:

Additional context
Cpp Properties:

{
  "compilerPath": "C:/MyMinGW/i686-9.2.0-static-release-win32-dwarf-rt_v6/mingw32/bin/gcc.exe",
  "cStandard": "c11",
  "cppStandard": "c++17",
  "configurationProvider": "vector-of-bool.cmake-tools",
  "compileCommands": "${workspaceFolder}/build/compile_commands.json"
}

Start by reproducing the reported C++17 snippet with the listed compiler and CMake configuration, then compare IntelliSense's diagnostic with the compiler's result. Trace the language-service handling of constexpr expressions involving captured lambda values; done means the valid expression is no longer flagged as an error.
