Well, you could always add a check to see if it’s pre-rendering (I believe prerender-spa injects a property into window), but that would have been more source code manipulation than I’d be comfortable with without switching to AST transforms anyway; actually I haven’t thought about that before. Since it’s done the way it is now, and possibly there could be other uses to an event like this, I’m gonna leave it as is.

I’m merging the PR and will work towards getting a minor version bump out, thanks for the issue!

Man, sorry for the bad language, but fuck IE. D:

The culprit seems to be the Event constructor, so it seems that a simple polyfill should be good to fix that. For now a workaround is to set useRenderEvent to false and to delete the line.
