What could be causing Rails 5.0.1 to add an iframe to my HTML, causing disruption to the links in the header navigation bar?

Currently, I am exploring the new features in Rails 5 by following Michael Hartl's tutorial for this version. Upon reaching the end of chapter 7, I observed that the links in the navigation bar only function when clicked below them. After inspecting the webpage, I discovered a strange 

div.lpiframeoverlay/iframe#lpiframeNNNNNNNN/#document/html
element that appears to have no real purpose other than intercepting events.

A search on github.com/rails for lpiframeoverlay yielded no results, suggesting that it may be related to one of the libraries being utilized in the code.

The source code includes a @media print rule to hide .lpiframeoverlay, so I decided to do the same universally. This resolved the issue, but I am still puzzled about the true function of this mysterious element.
