Monaco Editor Playground Code

const value = `typedef struct {
	xchar class;
} foo;`;

// Hover on each property to see its docs!
const myEditor = monaco.editor.create(document.getElementById("container"), {
	value,
	language: "cpp",
});

Reproduction Steps

1. Go to https://microsoft.github.io/monaco-editor/
2. Select Language c
3. Write

typedef struct {
    int class;
}

Actual (Problematic) Behavior

See that class is highlighted as keyword

Expected Behavior

class is no keyword in C, it should be highlighted like any other variable

Additional Context

No response

Start in the linked Monaco Editor Playground and reproduce the highlighting with language set to C and the supplied struct snippet. Trace the C syntax-highlighting definition used by Monaco; done when class is styled as an ordinary variable in C rather than as a keyword.
