 I was checking Appearance >> Themes using keyboard only: Tab, Shift+Tab
 and Enter. When I open the '''first and active''' theme modal dialog
 window, focus is acting weird.

 1. Focus is not set on the first focusable element. It goes to the
 Customize link.
 2. Focus does not stay inside the modal dialog window when tabbing.
 3. Both of these works fine when I open the second, non active theme.

 When I open any '''non active theme''' modal dialog I noticed also couple
 of focus issues.

 1. I can't focus on Delete theme button when tabbing trough the theme
 modal window on non active theme.
 2. But when focus is on Show previous theme button I can focus the Delete
 theme button when I use Shift+Tab.
 3. But then again if I continue Shift+Tab, focus is locked between Show
 previous theme and Delete buttons.
