Lines hidden by breadcrumb in the post editor footer

Hi,

The post editing page has a small footer containing a breadcrumb (kind of a navigator in the post structure). Useful but unfortunately, this footer is often hiding the last lines of the edit content which is rather annoying. See screen capture here : https://www.dropbox.com/s/cd6xww120fygq59/Footer_bug.jpg?dl=0 .

I couldn’t find any way to fix this or to prevent the breadcrumb from being displayed.

Thanks in advance.
