Thanks @stkb, this was an issue I was aware of but I clearly had forgotten to document it! There are some finicky limitations in generating downloads from a background page in Edge which is the cause of this issue. I will bring it up with Microsoft and if they don't have a workaround then I'm sure they'll add it to their issue tracker.

There is a fix from Microsoft coming for #24, but I'm not 100% sure that it will fix this issue because there seems to be some extra issues around the fact that this particular download is triggered from a background page. I will let them know about this extra factor and hopefully they can fix it at the same time.
