Doesn't work with show-whitespace-mode: no syntax highlighting of comments

What steps will reproduce the problem?
1. Turn on js2-mode (`M-x js2-mode`)
2. Check that comments and JSDoc comments are highlighted properly
3. Turn on show-whitespace-mode (`M-x show-whitespace-mode`)
4. Just in case run `M-x font-lock-fontify-buffer`

What is the expected output? What do you see instead?

Comments are not syntax highlighted at all, and use default face.  Instead
of using `font-lock-comment-face` they have 'nil' face (checked with text
properties from menu).

What version of the product are you using? On what operating system?

js2-mode version 20090723, show-whitespace-mode 2.1, GNU Emacs 21.4.1
(i386-redhat-linux-gnu, X toolkit, Xaw3d scroll bars), GNU/Linux
2.6.14-11.1.aur.2

Please provide any additional information below.
