ok, so because of flushing in nsDocLoader::DocLoaderIsEmpty we re-enter the method and end up clearing document request.

https://treeherder.mozilla.org/#/jobs?repo=try&revision=4dda0bdc51eb0e9d69b4f741af752fb2805f8ccc I went through couple of other options, but I think this quick-and-dirty is actually the best and safest. The re-entrancy happens when we after layout flush run script runners and stop frameloader's docshell.

Is there a more direct way to test this kind of thing? The fragile setTimeout cascade was hard to work with and won't make a reliable regression test.

perhaps dholbert might be able to comment about that, given that this is about svg:use, which does some rather unusual stuff in layout.

Sorry, I haven't had a recent enough interaction with the <use> mechanics (and the flushes / loader stuff involved here) to have a solid suggestion for comment 6.
