In full trace view of longer duration trace, spans are missing in trace view.

The query for fetching spans is initiated for 1hr window, if spans (async process or any late arrival spans) are not in that duration they aren't being fetched for full trace view, resulting in incomplete trace.

Query for 1hr window :
{ spans( limit: 1000 between: {startTime: "2021-09-20T01:48:18.320Z", endTime: "2021-09-20T02:48:18.320Z"} filterBy: [{operator: EQUALS, value: "000000000000000035f15d898a838751", type: ID, idType: TRACE}] ) { count total __typename } }
Result :
{ "data": { "spans": { "count": 406, "total": 406, "__typename": "SpanResultSet" } } }

Query for longer window:
{ spans( limit: 1000 between: {startTime: "2021-09-20T00:48:18.320Z", endTime: "2021-09-20T15:48:18.320Z"} filterBy: [{operator: EQUALS, value: "000000000000000035f15d898a838751", type: ID, idType: TRACE}] ) { count total __typename } }

Result:
{ "data": { "spans": { "count": 621, "total": 621, "__typename": "SpanResultSet" } } }
