Erase function of QJsonObject delete the wrong (key, value) pair in 5.15.0 beta4, It is working fine with 5.14.x.
Please refer to the attached sample where a test.json is parsed using QJsonObject. On erasing the pair with key as "xyz", It deleted the wrong pair with key as "test1".
{
	"Arr1": 
	[
		{
			"Count": 1,
			"Arr2": 
			[
				{
          "xyz": "data2",
          "test1": "data1",
          "Arr3" :
          [
            {
              "abc": "data3",
              "test2" : 1
            }
          ]
				}
			]
		}
	]
}
Output in Qt 5.15.0 :
Before erase propData =  QJsonObject({"Arr3":[{"abc":"data3","test2":1}],"test1":"data1","xyz":"data2"})
propfind key =  "xyz"
propfind value =  QJsonValue(string, "data2")
After erase propData = QJsonObject({"Arr3":[{"abc":"data3","test2":1}],"xyz":"data2"})
