Whitespace mode "shows" the tabs in two (independent) ways:

1. "Colorizing" the tab whitespace with some color (face tabs)
2. Add a mark in the whitespace space like | or � (tab-mark)

The whitespace-tab face applies only to 1, but I don't find how to make
it apply to 2


Define the whitespace-tab face foreground and background
(setq-default whitespace-style '(faces tab-mark))
(whitespace-mode 1)
TAB

I see: the �, but it is always white, independently of whitespace-tab face.
