[andrewtelnov]

The original issue was created in SurveyJS support desk.
Here is the minimum code to reproduce the issue:

    var json = {
      elements: [
        {
          type: "matrixdynamic",
          name: "countries",
          indent: 1,
          title: "Countries",
          columns: [
            {
              name: "country",
              hasOther: true,
              choicesByUrl: {
                url: "https://restcountries.eu/rest/v2/all",
                valueName: "name",
              },
            },
          ],
          rowCount: 1,
        },
      ],
    };
    var survey = new Survey.Model(json);
    survey.data = {
      countries: [{ country: "Albania", "country-Comment": "description" }],
    };
