It looks like page *size* settings aren't being respected here, either!

At least, it looks like that's happening in [this autoland test-failure log](https://treeherder.mozilla.org/logviewer?job_id=380848019&repo=autoland&lineNumber=136240), for [some tests](https://hg.mozilla.org/integration/autoland/rev/d376decbcba0#l10.30) that use a 5in-by-5in square sheet of paper via the following in printpreview_helper.xhtml:
```
      settings: {
        paperWidth: 5,
        paperHeight: 5,
        paperSizeUnit: Ci.nsIPrintSettings.kPaperSizeInches,
```

(That log triggered a backout due to this test failure -- the tests in question just need higher fuzzy annotations to account for this bug -- but I noticed the paper-size seems to be a not-getting-respected setting not just the unwriteable margins.)

(That log triggered a backout due to this test failure -- the tests in question just need higher fuzzy annotations to account for this bug -- but while reviewing the screenshots in the log, I noticed the paper-size seems to be not getting respected.  So it's not just the unwriteable margins.  See screenshot in next comment.)
