When setting the Frontpage to a static page, sidebar content is misaligned.
The following screenshot shows the frontpage template and no content in the 'Content Sidebar'. Since there's no content in the 'Content Sidebar', the template displays the 'Twenty Fourteen Ephemera Widget'.
As you can see, the sidebar content is displayed beneath the page content, rather than in the right-hand sidebar, like it should. This happens when it's displaying the 'Ephemera Widget' content and when you have actual content added to the 'Content Sidebar'.
Also, the 'Primary Sidebar' is not displayed at all.
#secondary has a negative left margin which means that it displays offscreen.
Using 3.8-beta-1 and Twenty Fourteen. The only plugin currently activated is the WordPress Beta Tester plugin
