I use (Global) Whitespace Mode with trailing spaces highlighted
(foreground is bold yellow) but *normal* spaces are supposed to be
invisible (foreground color is the same as the default background).

However, MHTML Mode, within CSS or JavaScript blocks, doesn't respect
these settings. The dots representing all spaces display in the default
foreground color, or in the color of the nearest highlighted text
token.

Exact steps to duplicate:

Open an HTML file containing CSS and/or JavaScript blocks, with Emacs
reset to defaults.

  ↪ emacs -Q ./foo.html

Enable MHTML and Whitespace modes.

  M-x mhtml-mode RET
  M-x whitespace-mode RET

Set normal spaces to be invisible (foreground color same as
background).

  M-x customize-face RET
  whitespace-space RET

-- then uncheck background color, set foreground color to same as
default background (white).

Back to the HTML document now...

  M-x previous-buffer

Don't do special highlighting for space indentation.

  M-x whitespace-toggle-options RET C-i

Don't to special highlight for long lines.

  M-x whitespace-toggle-options RET l

Dots representing nontrailing spaces should no longer be visible, but
in <style> and <script> blocks, they still are.

I think the bug here is that whitespace mode ultimately calls
font-lock-add-keywords to do its work.  However, mhtml-mode captures the
value of font-lock-keywords on a per-submode basis.  So, the change is
not detected.

mhtml probably needs some form of indirection in font-lock-keywords, so
it can apply the subregion matchers as well as any introduced by other modes.
I'm not sure there's a way to do this today.  The easiest would be some
form of a function in the list, where the function would return
font-lock-keywords rather than matches.

Tom
