[data grid] valueGetter fallback not applied in renderCell

Current behavior

Consider the following column definition:

 ARRAY: {
    display: "flex",
    renderCell: (params) => {
      console.log(params.value);
      return <ChipsColumn params={params} />;
    },
    valueGetter: (value) => {
      if (!value) return [];

      const formattedValue = value
        ? Array.isArray(value)
          ? value
          : [value].filter(Boolean);
      return formattedValue;
    },
  },

I am passing an array to render Chips, and although I’ve provided a fallback value (an empty array) in the valueGetter, when no row/value is YET available (fetching rows), undefined is still passed to renderCell. Is it possible to modify this behaviour so that the valueGetter can be used to define fallback values?

To help us diagnose the issue efficiently, could you provide a stripped-down reproduction test case using the latest version? A live example would be fantastic! ✨

For your convenience, our documentation offers templates and guides on creating targeted examples: Support - Bug reproduction

Just a friendly reminder: clean, functional code with minimal dependencies is most helpful. Complex code can make it tougher to pinpoint the exact issue. Sometimes, simply going through the process of creating a minimal reproduction can even clarify the problem itself!

Thanks for your understanding! 🙇🏼
