Change in theme.css breaks customer CMS page layout

In the Dublin release, the CSS attribute [body {height:100%;} ] has been introduced for UI enhancements on theme.css.

 

This can cause a broken layout on pre-upgrade settings in customer CMS pages.

The attribute [ body {height:auto;} ] is expected in the CMS stylesheet.

 

If this occurs after a Dublin upgrade, change the CMS base stylesheet to:

BODY{ height: auto;}
