jsfiddle.net doesn't load correctly

[zspitzer]

latest servo windows nightly build, win10 64 (creators update)

I wanted to try this test out which has been causing safari lots of grief

The terminal shows ERROR:script::dom::bindings::error: Error at :0:0 SecurityError: The operation is insecure. which suggests this is an issue that would be improved by cross-origin wrappers.

just the embedded version progresses further and loads, but the rendering stalls

Rendering no longer appears to stall for the embedded version at https://jsfiddle.net/xkryswj3/embedded/result/. The error observed at https://jsfiddle.net/xkryswj3/ is now:

[2019-08-21T19:11:50Z ERROR script::dom::bindings::error] Error at https://jsfiddle.net/js/_dist-editor.js?update_06_08_2019_1:1:1124472 editor is not defined

Which suggests that this relies on contenteditable, sadly.
