ace-window and font face not working

[Luca Ferrari]

Hi all,
running Emacs 27.2, and I've try to setup the font face for when
ace-window activates (the window number):

(custom-set-faces
         '(aw-leading-char-face
           ((t (:inherit ace-jump-face-foreground :height 30 :weight
bold :foreground "#00ffff" :background "#0000ff")))))


The color for the foreground and background is correctly set, but the
height does not seem to work. At least in terminal mode, that is how I
use Emacs in this configuration.

Any idea?

Thanks,
Luca
