I just did a Try run with some Test-Verify tasks for (slightly-modified) [test_bug1261673.html](https://searchfox.org/mozilla-central/source/dom/html/test/test_bug1261673.html), and I got this failure back from one of the tasks:

```
TEST-UNEXPECTED-FAIL | /tests/dom/html/test/test_bug1261673.html | changed preference: doh-rollout.doneFirstRun
```
https://treeherder.mozilla.org/logviewer?job_id=413088341&repo=try&lineNumber=3986

This test does not in fact toggle that pref (or have anything to do with that pref); instead, this pref apparently gets toggled in the background, lazily, on the first time we do some DoH (DNS-over-HTTPS) activity, or something like that.

So: this isn't really a legit test failure. We should add this pref to testing/mochitest/ignorePrefs.json

Here's the log with the failure:
