 I decided I'd do some testing with the 4.9 release (currently using RC2)
 and noticed on the about page, when you scroll down there are some titles
 that follow you down the page. It seems that when you get to the bottom of
 a container, the title disappears as you scroll on down to the next
 section. If you scroll back up again then the title will suddenly appear
 once again.

 The `.floating-header-section h2` element should have a position of
 absolute when it gets scrolled down to the bottom boundary of that
 section. Currently, when you reach the bottom, the `top` attribute gets
 reset to 0 so it looks like it's flashing when really it's just jumping up
 to the top.

 A fix for this would be to set a position of absolute when the title hits
 the very bottom of it's section container so it appears to stick to the
 bottom.
