I have added a custom event listener to copy/cut of Rich text (HTML) from an element (say elementId). Now when I copy partial ordered list tags, it converts them to unordered list items. This happens due to partial copying the list. Is there any way to solve this ?

document.getElementById(config.editorEl).addEventListener('copy', function(event) {
    const range = window.getSelection().getRangeAt(0);
    const content = range.cloneContents();
    const div = document.createElement('div');
    div.appendChild(content);
    $(div)
    .find('.remove_this_class')
    .contents()
    .unwrap();
    event.clipboardData.setData('text/html', div.innerHTML);
    event.preventDefault();
    });

Summary: when I copy partial ordered list tags, custom copy handler converts them to unordered list items. How to retain the same ? I see many RTFs have this working.
