Initialize iframe viewport immediately
This is probably a significant cause of unstable test results, and it finally bothered me enough to fix it. The solution isn't great for performance (a sync layout query every time a iframe is added to a document), but performance needs to follow correctness.

Previously we'd omit it since it was merely an explicit way of requesting the
default behavior. But the spec has changed such that it's not necessarily
equivalent to the default anymore:
https://drafts.csswg.org/css-align/#overflow-values
(Technically the behaviors are probably still equivalent in our implementation,
pending bug 1451380, but we don't have to publicize that via our
serialization.)

We could keep using ParsedCaseSensitivity::CaseSensitive as a temporary stand-in
for "case-sensitive or maybe not depending on what HTML says" until we check the
attribute list, but it seems better to make that explicit.

This allows to experiment with other hash maps easily rather than
depending on what hashglobe::fake::HashMap dereferences to.
In particular I wrote it while trying to get a build working with hashbrown.

Disable referrer-policy tests for frequent intermittent failures.
This is hitting us really hard on the taskcluster WPT runs, so I'm going to disable them until we can investigate it properly.
