When viewing a shared story with changes it incorrectly shows the “show story changes” toggle but the changes are already showing. I would expect that if that toggle was shown then no changes would be shown and to see them you would need to click the toggle. Once you click it to “show” the changes nothing happens but the toggle changes to “hide changes”, after this the functionality works as expected.
I am using Windows 10 with Firefox 48.0a2
