X-widget: Buffer is not being re-displayed

[A6GibKm]

Same setup of opening a file with xwidget as the previous two bugs. This time around run counsel-M-x to extend the buffer and the xwidget buffer will not be re displayed after quiting counsel-M-x.

Steps to reproduce:

With the following .emacs file

(require 'package)
(setq package-enable-at-startup nil)
(add-to-list 'package-archives '("melpa" . "http://melpa.org/packages/"))
(add-to-list 'package-archives '("gnu" . "http://elpa.gnu.org/packages/"))
(package-initialize)

(unless (package-installed-p 'use-package)
  (package-refresh-contents)
  (package-install 'use-package))

(eval-when-compile
  (require 'use-package))

(use-package counsel
  :ensure t)

• Open a xwidget as (xwidget-webkit-browse-url "file://home/USERNAME/some.html")
• Run counsel-M-x
• Press C-g to cancel counsel

The counsel minibuffer should disappear and the xwidget should be re displayed, see screencast below.

Not reproducible in the master branch of Emacs. Incidentaly, vanilla emacs is providing a way worse experience than pgtk due to some flashes of the previous buffer :tada:.

I think it should be possible to reproduce this using C-x C-b to list buffers. No need for the config or counsel.

confirmed with counsel-M-x and C-g.
