If those parts are never displayed, then it's "normal" (the default setup should fontify them stealthily in the background at some time, but that can be changed and it can take a while anyway, so better not to count on it). If those parts are displayed and yet they're not fontified it's a bug which you should report via M-x report-emacs-bug. > Customizing font-lock-support-mode and setting it to lazy-lock-mode > eliminates the problem.

Lazy-lock has some known bugs (I remember some missing on-screen fontification using outline-minor-mode, for example), is less efficient, is not developed any more, and will be marked obsolete in Emacs-22.
