I've spoken with one of our developers and he explained:
@Matt_Coady: When you normally make a page you'd put your content into the actual sections. When you collapse them it'll take the content with it. The trouble with our system is the content all sits together on a layer above the page sections, totally separate of each other. The reason for this is that it lets the user freely position content anywhere, including having content from one page section show up in another page section.
There's no easy way of working around it, though @Hristian seems to have built a workaround. I imagine if you contacted him directly he might be able to see if it's something that he can help you out with, but in this situation I unfortunately can't provide a script.
Hope that sheds some light on the situation!
