The following function returns `forward` if user selected text from the left to right. It returns `backward` in the other case.
const getDirection = function () {
const selection = window.getSelection();
const range = document.createRange();
range.setStart(selection.anchorNode, selection.anchorOffset);
range.setEnd(selection.focusNode, selection.focusOffset);

return range.collapsed ? 'backward' : 'forward';
