When I click, the page is split in two and neither is fully visible.
There's an X button on the top-left corner of the 'Table of Contents' that should slide it away.
I see no button. Pic below.
Hmm.. that's a bug. If you could let me know what browser and device you're using, I might be able to reproduce this and fix it as soon as possible.
This should be fixed now.
