auto-hide does not work on *Warnings* buffer when display-warning is called

[gvannoye]

Minimal configuration:

(use-package popper
:custom
  (popper-reference-buffers
   '(("\\*Warnings\\*" . hide)))
  :init (popper-mode +1))

To reproduce the bug, execute the following snippet:

(display-warning :warning "test")

Expected behavior: the *Warnings* buffer should not be displayed. Seen behavior: the *Warnings* buffer is displayed.

Thanks a lot for the package and any help you could bring!

The 'hide' setting only applies once, when the buffer is created. If you want the window to never show at all, you can add a display-buffer-alist entry for "\Warnings\".
