[Reg 6.5 -> 6.7] Anonymous function on a signal results in QML Linter error when compiler warnings are enabled

Using an anonymous function on a signal results in the following QML Compiler error when compiler warnings are enabled for the QML linter:

Warning: [..]/test/Main.qml: Object type function is not derived from QObject or QQmlComponent. You may need to fully qualify all names in C++ so that moc can see them. You may also need to add qt_extract_metatypes(<target containing >). [compiler]

The error shows under Compile Output in Qt Creator when the QML linter is configured to show compiler errors, like so:

CompilerWarnings=warning.

No warnings appear under Issues in Qt Creator when this issue occurs.

The following examples trigger the error.

Example 1:

    MouseArea {
        anchors.fill: parent
        onEntered: () => {
            console.log("Entered")
        }
    }

Example 2:

    TextEdit {
        anchors.fill: parent
        onEditingFinished: () => {
            console.log("Finished")
        }
    }

Using the older anonymous JS function syntax also triggers the error:

Example 1b:

    MouseArea {
        anchors.fill: parent
        onEntered: function() {
            console.log("Entered")
        }
    }

Example 2b:

    TextEdit {
        anchors.fill: parent
        onEditingFinished: () {
            console.log("Finished")
        }
    }
