I do the following, starting from `emacs -Q`:

- Evaluate the following `set-face-attribute` calls (with FRAME set to nil, no
  use of `unspecified`):

  (set-face-attribute 'isearch nil :background nil :foreground "#d33682")
  (set-face-attribute 'isearch-group-1 nil :background "lightskyblue1" 
:foreground "#d33682")
  (set-face-attribute 'isearch-group-2 nil :background "DarkSeaGreen1" 
:foreground "#d33682")
  (set-face-attribute 'lazy-highlight  nil :background nil :foreground nil :box 

- Start isearch in any buffer and observe the changed faces.

- Create a new frame with `C-x 5 2`.

- Start isearch again and observe that the faces are a mix of old an new. Most
  notably are the background colors, which I'm trying to set to nil but which
  are present in the newly created frame. The same for the foreground of
  lazy-highlight. The box of lazy-highlight does appear, though.

- Now evaluate the other four calls to `set-face-attribute`:

  (set-face-attribute 'isearch t :background 'unspecified :foreground "#d33682")
  (set-face-attribute 'isearch-group-1 t :background "lightskyblue1" 
:foreground "#d33682")
  (set-face-attribute 'isearch-group-2 t :background "DarkSeaGreen1" 
:foreground "#d33682")
  (set-face-attribute 'lazy-highlight  t :background 'unspecified :foreground 
'unspecified :box "#d33682")

- Create another frame with `C-x 5 2`.

- Start isearch; now the faces in the newly created frame are what I expect them
  to be, i.e., the same as in the initial frame.

Tested on Emacs 28.1.
