Merge pull request #512 from xamarin/fix-issue-504

> After discussing with @jonpryor, we aren't entirely sure if this fix will work at runtime. I'm going to do some additional testing to see. 

We did similar fixes quite often in early days.

> Please hold off on merging this while I'll investigate. 

> Thanks!
