[BUG] Json Editor not showing more data when scrolling down #395

What I Expected

Assign data to JSON Editor, and display all data without any problem

Current State

When scrolling down, I couldn't see more data as expected.
As shown in the attached image, data is not displayed after the 35th item.

What I have tried

1. Validate Data

The data I put into the JSON Editor is as follows:

[
  {
    "chapterName": "9까지의 수",
    "conceptId": "416",
    "preRequisiteChapterName": "",
    "preRequisiteConceptId": ""
  },
  {
    "chapterName": "여러 가지 모양(1)",
    "conceptId": "417",
    "preRequisiteChapterName": "",
    "preRequisiteConceptId": ""
  },
  {
    "chapterName": "덧셈과 뺄셈(1)",
    "conceptId": "418",
    "preRequisiteConceptId": "416",
    "preRequisiteChapterName": ""
  },
  {
    "chapterName": "비교하기",
    "conceptId": "419",
    "preRequisiteChapterName": "",
    "preRequisiteConceptId": ""
  },
  ...more data folow
]

I have assigned the same data to the JSON Explorer, and I have confirmed that there is no issue with the JSON data.

2. see console to get any error message

There was nothing useful at console.

Questions

Is there a limit to the number of items that can be placed in the JSON Editor?
Do I need any additional configurations?

summary

1. Json Editor not showing more data when scrolling down
2. data is fine. Confirmed by json explorer
3. Nothing useful at console
4. limit to the number of items? or Need additional configurations?
