After configuring "objectHash", jsondiffpatch.formatters.html ShowUnchanged does not take effect

[liangxuemin]

After "objectHash" is configured, jsondiffpatch.formatters.html.showUnchanged cannot show the same value with different positions

  let that = this;
  let secodeLists = JSON.parse(JSON.stringify(secodeData));
  let deltas=null;
  let diffpatcher = jsondiffpatch.create({
    objectHash: function(obj,index) {
      return obj.serviceCode ||obj.columns || '$$index:' + index;
    },
    arrays: {
      // default true, detect items moved inside the array (otherwise they will be registered as remove+add)
      detectMove: true,
      // default false, the value of items moved is not included in deltas
      includeValueOnMove: false
    },
    propertyFilter: function(name, context){
       console.log('name', name, context)
    },
    cloneDiffValues: false
  });
  this.diffpatcher = diffpatcher;
  document.getElementById('visualsuat').innerHTML =''
  tijiaodiff()
  function tijiaodiff(){
    if (!firstData && !secodeLists) return;
    deltas = diffpatcher.diff(firstData, secodeLists);
    // console.log('deltas', deltas, JSON.stringify(deltas))
    if (deltas) {
      that.isDisabled = false;
      document.getElementById('visualsuat').innerHTML = jsondiffpatch.formatters.html.format(deltas, firstData);
    } else {
      document.getElementById('visualsuat').innerHTML ='无对比结果'
    }
    if (!that.showUnchange) {
      jsondiffpatch.formatters.html.hideUnchanged();
    }
  }
  jsondiffpatch.formatters.html.showUnchanged(
    target.checked,
    null,
    800
  );
