As noted in ​https://github.com/dojo/dojo/commit/bfea978ffd6e7a0606ad677e457e7079e42a937d#commitcomment-20930838 , unless I am misunderstanding, I think there are two different issues here. The latter issue is such that I don't believe you should be able to use getComputedStyle across domains. Perhaps this was failing silently before and now it's failing via an error? For the former issue, I'm thinking we may need to do something to detect win.global.window.parent vs. win.global.window and pick one based on permission/existence perhaps? Regardless, we'll investigate again.
