Describe the bug

• OS and Version: Windows 10 2004
• VS Code Version: 1.41.0
• C/C++ Extension Version: 0.26.3-insiders2
• Other extensions you installed (and if the issue persists after disabling them): python
• A clear and concise description of what the bug is.
  If the first template argument is a pair, intellisense seems to skip the next argument.

To Reproduce

1. open a new file
2. populate with

#include <queue>
#include <utility>

using namespace std;

int main()
{
    return 0;
}

3. before line "return 0", start a new line with "priority_queue<pair<int, int>"
4. IntelliSense says I'm going to input _Sequence
5. append ", "
6. IntelliSense says I'm going to input _compare, however I'm going to input _Sequence.

Expected behavior

IntelliSense should probably underline _Sequence for me.

Additional context

I tried:
testing in windows with Mingw gcc 8.2.0
testing in WSL with gcc 9.2.1
both observes the issue.
