The user wants to use string "span style" tag as edittools element.
While using of "& #32;" instead space between "span" and "style", is look ok on [[Mediawiki:Edittools]] itself, but still leads to splitting of this element in the edit-mode (the buttons are broken at the space between "span" and "style").
Example: http://www.mediawiki.org/w/index.php?title=MediaWiki:Edittools (please compare this look - http://www.mediawiki.org/w/index.php?title=MediaWiki:Edittools&oldid=562971 , and look in the edit-mode - http://www.mediawiki.org/w/index.php?title=MediaWiki:Edittools&action=edit )
