I don't know the actual reason but I would place a high level of probability on it being security related. Note that this is an area that I am not great shakes on, but for the sake of trying an answer, the following
.
As one example as to how a vulnerability might exist is that an epub is pretty much a zip file containing a website. Therefore there is a difference in vulnerability between running scripts in an epub hosted by the website being browsed (Edge can open an epub directly without the user downloading it) and an epub that the computer user has downloaded from somewhere else (which Edge also will do).
I am aware that there exist or have been recent script vulnerabilities in at least iBooks (uses Webkit?) and ADE (uses IE I think, it requires, or did require Internet Explorer to be installed?). Others likely have problems too.
There-yer-are either some bait for someone who knows more to expand on
or, more likely, rip to pieces
