Can't sort a dired buffer after embark-export

[jwnki]

Hi, thanks for this great package! I believe I found a bug related to embark-export and dired. When exporting file candidates to a dired buffer, I can't sort the resulting buffer.

To reproduce:

(require 'package)
(package-initialize)
(package-install 'embark)
(global-set-key (kbd "C-c C-o") #'embark-export)

And then:C-x C-f (find-file) C-c C-o. In the resulting dired buffer press s to toggle sorting. You can see that the sorting style changes (modeline indicator switches from "dired by name" to "dired by date", and some white space disappears), but the buffer remains unsorted.
