Function ImageCaptionSpace throws TypeError: Cannot read properties of null (reading 'parentElement')

[petrovy4]

Expected behavior.

ImageCaptionSpace handles edge cases correctly and does not throw error

Actual behavior.

Function ImageCaptionSpace assumes that element returned by selection.element() always has at least 2 parents:

...
    function ImageCaptionSpace(sel_el, e) {
      // https://github.com/froala-labs/froala-editor-js-2/issues/4429
      var _ref = sel_el && sel_el.parentElement,
        parentElement = _ref.parentElement;
...

which is not always correct and should be corrected to avoid exceptions. For example this way:

...
        parentElement = _ref?.parentElement;
...
