CSS Grid Layout in Chrome doesn't seem to work properly with over 1000 rows

Question

I created an example of a moving grid with fixed headers using the CSS Grid Layout and Sticky position technologies. For convenience, the contents of the grid are generated by a script, which I think works well.

function fillGrid(selector, rows) {
  let cols = 3;
  let grid = $(selector);
  
  grid.empty();
  
  //cr header
  grid.append($('<div>').addClass('hcr').text('#'));
  
  //col headers
  for (let c = 1; c <= cols; c++) {
    grid.append($('<div>').addClass('hc').text(`Column ${c}`));
  }
  
  for (let r = 1; r <= rows; r++) {
    //row header
    grid.append($('<div>').addClass('hr').text(r));
    
    //cells
    for (let c = 1; c <= cols; c++) {
      grid.append($('<div>').addClass('c').text(`Cell ${r}-${c}`));
    }
  }
}

$('#reload').click(e => {
  var rows = Number.parseInt($('#rows').val());
  fillGrid('#grid1', rows);
})

$(document).ready(function() {
  fillGrid('#grid1', 10);
});

body {
  font-family: 'Segoe UI', sans-serif;
  font-size: 12px;
}

.grid {
  display: grid;
  width: 600px;
  height: 300px;
  grid-template-columns: 40px 200px 100px 500px;
  grid-auto-rows: min-content;
  border: 1px solid #ccc;
  overflow: scroll;
  margin-top: 20px;
  background-color: #aaa;
  margin-right: 10px;
}

.hcr, .hc, .hr {
  background-color: #ddd;
  border-right: 1px solid #ccc;
  border-bottom: 1px solid #ccc;
  padding: 2px;
  position: sticky;
}

.hcr {
  top: 0;
  left: 0;
  z-index: 1;
  text-align: center;
}

.hc {
  top: 0;
  white-space: nowrap;
}

.hr {
  left: 0;
  text-align: center;
}

.c {
  padding: 2px;
  border-right: 1px solid #ccc;
  border-bottom: 1px solid #ccc;
  background-color: #fff;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div>
  <input type="text" id="rows" value="10" />
  <input type="button" id="reload" value="Reload" />
</div>
<div class="grid" id="grid1"></div>

Run codeHide result

Up to 999 lines, the grid works fine. When more than 999 lines are loaded, only cells up to line 999 are displayed, and the following cells are not located correctly above the header of line 999.

The same example works correctly in Firefox 56 and Edge 16 (version 16299).

Where am I mistaken?
