It seems that this bug occurs when the JSON is in a single line, but it does not happen with a formatted JSON.

{"metricId":"2507040FA0B2BS000000000000374705","metricType":"RATIO","metricUnit":"%","spaceId":"8206","metricCnName":"转化率","metricDesc":"计算成功申请数量占比","metricName":"apply_success_rate","metricAlias":"[\"成功率\",\"申请成功率\"]","metricExpression":"front_agent_manager_app_intake.success_apply_ct / front_agent_manager_app_intake.total_apply_ct","metricSql":"select front_agent_manager_app_intake.success_apply_ct / front_agent_manager_app_intake.total_apply_ct from front_agent_manager_app_intake","metricDiff":"同比、环比","metricStatus":"Y","tableOfMetric":["front_agent_manager_app_intake","front_agent_manager_app_intake"],"extraInfo":{"owner":"data_team","updateFrequency":"daily","dataSource":"tidb"}}

It seems to appear occasionally.

It seems that an extra line was executed; pressing Ctrl+Z corrected it.

Here, EditorProps.onChange was executed three times.

修改下面代码：EditorProps.onChange

onChange={contents => {
            const cleaned = contents
              .split("\n") // 按行切割
              .filter(line => line.trim() !== "") // 过滤掉空行（只含空格也算）
              .join("\n");
            setContents({ cleaned, skipUpdate: true });
          }}
