# In Lithium, the TOC drawer only remembers your position if
# the page that you're reading corresponds to a TOC entry
# exactly. Which is to say, if you left off on page5.html,
# there needs to be a TOC line with href="page5.html" or else
# the TOC drawer will be in the default position at the top of
# the list and not highlight the current chapter. Any #anchor
# in the href will break this feature. So, this code will make
# the first <hX> on a given page not have an #anchor. If you
# have a significant amount of text on the page before this
# header, then this will look bad. But for the majority of
# cases I expect the first header on the page will be at the
# very top, or near enough that the Lithium fix is still
# worthwhile.
