clear:both removed from line 61 .menu-movil parent div in header.php breaks page

Hello,

On line 61 of header.php, which was moved up from outside its current parent div, clear:both; was removed from the style attribute when the line was moved. This is breaking the layout of our pages such that the content area is shrunk to the width of the menu. The clear:both; needs to be re-added to that div. I’m currently having to add it in the Editor, which of course is overwritten with each theme update.
