Reader View used to work with SUMO articles, but not anymore. To have our tour work as we intend we need the pre-populated SUMO articles viewable in Reader View. https://support.mozilla.org/en-US/kb/save-sync-and-read-pages-anywhere-reading-list

I can confirm that this is an issue affecting both Nightly 39.0a1 (2015-03-30) and Aurora 38.0a2 (2015-03-30), using Ubuntu 14.04 (x64) and Windows 7 (x64).
This sounds like a dupe of bug 1147626.
Marking this as depending on bug 1147626 for now so we can watch for the changes to land and then test that this is fixed.
