Bug 1653164: fix(webgpu): actually show props. for...

      desc.isFallbackAdapter = adapter.isFallbackAdapter;

      desc.name = adapter.name;

      if (desc.name === undefined) {

        desc.name = null; // JSON has no `undefined`.

      }

      if (adapter.requestAdapterInfo) {

        // Firefox doesn't have this yet.

        const info = await adapter.requestAdapterInfo();

        desc[`requestAdapterInfo()`] = info;

      } else {

        desc.requestAdapterInfo = null;

      const adapterInfo = await adapter.requestAdapterInfo();

      // We can't directly enumerate properties of instances of `GPUAdapterInfo`s, so use the prototype instead.

      const adapterInfoObj = {};

      for (const k of Object.keys(Object.getPrototypeOf(adapterInfo)).sort()) {

        adapterInfoObj[k] = adapterInfo[k];

      }

      desc[`requestAdapterInfo()`] = adapterInfoObj;

      desc.features = Array.from(adapter.features).sort();
