What determines the amount of error displayed in the Problems tab

[TryerGit]

I am on Windows and call MSBuild like so in tasks.json:

{
        "label": "winbuilddebug",
        "type": "process",
        "command": "msbuild",
        "args": [
            ".vscode/windows.vcxproj",
            "/property:GenerateFullPaths=true",
            "/property:Configuration=Debug",
            "/property:Platform=x64",
            "/t:build",
            "/consoleloggerparameters:NoSummary"
        ],
        "group": "build",
        "presentation": {
            "reveal": "silent"
        },
        "problemMatcher": {
            "base": "$msCompile",
            // "fileLocation": "absolute"
        }
    },

The Terminal tab displays the full error like so:

C:\Users\TryerGit\Insync\TryerGit\GoogleDrive\research_programming\General_C_and_C++_Programming\VSCode_Windows\code\main.cpp(8,2): error C4996: 'scanf': This function or var
[the error message itself is split here via a newline thus the error message spans multiple lines]
iable may be unsafe. Consider using scanf_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details. [C:\Users\TryerGit\Insync\TryerGit\GoogleDrive\research_programming\General_C_and_C++_Programming\VSCode_Windows\.vscode\windows.vcxproj]

Now, when I then move to the Problems tab, this error is listed and clicking on it does take me to the file and line in question but the error message displayed is truncated like so:

main.cpp -> 'scanf': This function or var cpp(C4996) [Ln 8, Col2]

You will notice that only the first 4 or 5 words of the actual complete error message is displayed. Is there a way to fix this so that the full error message is displayed? That is, with the default $msCompile problem matcher, it seems it is unable to catch multiline errors and hence displays only the first line. What changes should be made to the problem matcher so that it captures the full error message in the Problems tab?

Seems to be a problem with VSCode folks itself? See microsoft/vscode#150285

Would be great if a way out is possible.
