I am unclear how this test failures is related to the code removal in this patch. The results.html file in the attached results archive indicates that the test crashed, but no crash log is included :(

r=me. The Windows-specific test failure is not related to this change.

Do you think it would be useful to developers if we generated a console message here, rather than just ignoring it?

I will update the patch to emit the following Security error message to the console when an HTML page tries to use the Set-Cookie meta tag:

The Set-Cookie meta tag is obsolete and was ignored. Use the HTTP header Set-Cookie or document.cookie instead.
