<button id='copyBtn'>
Copy to clipboard
</button>

const dataLengthMB = 150; // crashes 130 MB +
const dataLength = dataLengthMB * 1024 * 1024;

let dummyData = new Array(dataLength + 1).join( 'A' );

$('#copyBtn').on("click", event => {
  document.execCommand("copy");
});

$(document).on("copy", event => {
  event.originalEvent.clipboardData.setData('text/plain', dummyData);
  // event.originalEvent.clipboardData.setData('text/html', dummyData);
  event.preventDefault();
