<$projecttitle> & <$shortdate> don't work in header

Windows version 1.2.5: Yay for the new shortcodes <$projecttitle> and <$shortdate>! They were on my wishlist.

ALAS, they don’t seem to work in a compile header, which is exactly the place I want them to work!

Header:
<$projecttitle>, <$shortdate>, p. <$p>

Should print as:
MyProjectTitle, 8/17/12, p. 1

But actually prints as:
<$projecttitle>, <$shortdate>, p. 1

(only the page number is properly substituted)
