Unhandled exception on "ctrl+left/right-click" drag or "shift+right-click" drag on a chart

On a chart if I hold ctrl and try to drag with left-click or right-click or shift+right-click drag, then getting an exception.

After analyzing the code, I found that ctrl is treated as right-click, and if drag operation and right click then "options.moveFn(dx, dy);" function is not getting called which results in not updating "updates" for the dragTail() function that calls "_guiRelayout" with undefined updates and in that function exception is raised if updates are undefined. Pasting js code of these function below:

This issue can be replicated easily in plotly's samples as well. Just hold ctrl and drag with left/right-click, you can see error in console.

Attaching snapshot:

function onMove(e) {
  e.preventDefault();

  var offset = pointerOffset(e);
  var minDrag = options.minDrag || constants.MINDRAG;
  var dxdy = clampFn(offset[0] - startX, offset[1] - startY, minDrag);
  var dx = dxdy[0];
  var dy = dxdy[1];

  if (dx || dy) {
    gd._dragged = true;
    dragElement.unhover(gd);
  }

  if (gd._dragged && options.moveFn && !rightClick) {
    gd._dragdata = {
      element: element,
      dx: dx,
      dy: dy,
    };
    options.moveFn(dx, dy);
  }

  return;
}

// dragTail - finish a drag event with a redraw
function dragTail() {
  // put the subplot viewboxes back to default (Because we're going to)
  // be repositioning the data in the relayout. But DON'T call
  // ticksAndAnnotations again - it's unnecessary and would overwrite `updates`
  updateSubplots([0, 0, pw, ph]);

  // since we may have been redrawing some things during the drag, we may have
  // accumulated MathJax promises - wait for them before we relayout.
  Lib.syncOrAsync(
    [
      Plots.previousPromises,
      function () {
        gd._fullLayout._replotting = false;
        Registry.call("_guiRelayout", gd, updates);
      },
    ],
    gd
  );
}

function relayout(gd, astr, val) {
  gd = Lib.getGraphDiv(gd);
  helpers.clearPromiseQueue(gd);

  if (gd.framework && gd.framework.isPolar) {
    return Promise.resolve(gd);
  }

  var aobj = {};
  if (typeof astr === "string") {
    aobj[astr] = val;
  } else if (Lib.isPlainObject(astr)) {
    aobj = Lib.extendFlat({}, astr);
  } else {
    Lib.warn("Relayout fail.", astr, val);
    return Promise.reject(); // From here exception is raised
  }
  .... Rest of the code
}

Tái hiện lỗi trong các sample của Plotly bằng cách nhấn ctrl rồi kéo sang trái/phải hoặc nhấn shift rồi kéo sang phải, sau đó lần theo các hàm onMove và dragTail được hiển thị trong issue. Xác minh rằng thao tác kéo hoàn tất mà không truyền các bản cập nhật undefined vào _guiRelayout và ngoại lệ không còn xuất hiện trong console.
