// https://silbloom.myjetbrains.com/youtrack/issue/BL-3835 describes a problem that can occur when
// Url encoded filenames are stored for the coverImage data. One of the uploaded books
// in the library has coverImage data stored as
// <div data-book="coverImage" lang="*">
// The%20Moon%20and%20The%20Cap_Cover.png
// </div>
// and the image file was not being found by the server because a second level of encoding was
// applied before requesting the file. So this test arbitrarily applies a double level of Url
// encoding (the third time) to ensure that the server can handle it.
