Section 1

This page is checking whether previously-buggy sidebar behavior has been successfully fixed.

(Specifically, the bug showed up only when the "Allow" setting is used in combination with the "Continue from Previous Section" placement option.  This would make vestigal sidebars still display, which is wrong.

This section has a sidebar, which is correct and should show up.

This section also contains more text than it needs to.  This is just so that changes to the "Sidebar Position Layout" in the next section can show up correctly. (The expected behavior is different between "start new track" and "continue from previous section.")

This is probably enough paragraphs for that.

Section 2

This second section also has a perfectly-allowable sidebar, and is set to continue the previous track.  This should cause the blue sidebar to be "pulled up" to stack with the green one, and should also keep them together when viewing the page on narrow (phone-like) screens.

Section 3

This third section also has data for a sidebar, but we're going to set the "Sidebars" setting to "Allow," which should permit globally-defined sidebar content from Folder Settings, but not actually render any in-page sidebars!

That's the plan, anyway....
