Dominic Farolino: https://github.com/web-platform-tests/wpt/blob/master/html/semantics/scripting-1/the-script-element/moving-between-documents/move-back-iframe-fetch-error-external-module.html assumes that a slow stylesheet blocks module scripts from running. AFAICT, in Gecko, only the execution of a parser-blocking script can be deferred by a stylesheet. Where in the spec does it say that non-async (i.e. defer) module scripts wait on style?

I didn't write that test, so I'll try and reach out to the Googler that did and see if he can explain.
