Edit Book: Mark as Cover Page doesn't seem to work
While playing (and learning to code) about https:/
I am 95% nearly sure that I've reverted my changes (checked-out from my personal branch to master branch pulled from origin/master) but there are always quite a lot of possibilities that I've done something REALLY wrong and my code is what is actually breaking that feature...
I'm testing with the attached epub. Just try to mark any file as Cover Page.
