bug: problemMatcher property can't be defined in the global scope

[dongzhuoer]

task.json

{
    "version": "2.0.0",
    "presentation": {
        "reveal": "silent"
    },
    "problemMatcher": []
    ,
    "tasks": [
        {
            "label": "build",
            "type": "shell",
            "command": "echo haha",

            "group": {
                "kind": "build",
                "isDefault": true
            }
        }
        
    ]
}

Task -> Run Task... -> build, it will ask me to "select for which kinds of warnings to scan the tasks output" as if the problemMatcher definition in global scope has not taken effect.

But with the following, everything works fine.

{
    "version": "2.0.0",
    "presentation": {
        "reveal": "silent"
    },
    "tasks": [
        {
            "label": "build",
            "type": "shell",
            "command": "echo haha",
            
            "problemMatcher": []
            ,
            "group": {
                "kind": "build",
                "isDefault": true
            }
        }
        
    ]
}

If the property does can't be defined in the global scope, please add an explanation is the docs (search "Task properties can also be defined in the global scope")

Does this issue occur when all extensions are disabled?: Yes
