Some options not appearing in widget options when in customizer

[ghost]

The checkboxes are not visible for 'show featured image' and 'show post title'.

This only happens when using the customizer.

i found the issue.

The function is_widgets_page() has conditional for is_admin() but not is_customize_preview().

This means when users access the widget options through the customizer, (from the adminbar, not the dashboard) the styles for the widget options aren't loaded.

..and the checkboxes aren't showing as they have the class 'widget-control-save' which is automatically set to display: none, by the core customizer styling. I would do a pull request, but i'm slightly out of my depth.

I am having this issue as well…Could be related to new Wordpress Version?
