Fix style errors in TextDisplayer
Fix style errors in TextDisplayer

Style properties like width, height, and paddingTop should be set on
the style object, not the element directly.  Further, "float" is the
wrong name for the css float property in JavaScript.  This should be
"cssFloat".

These bugs were caught by a newer compiler.

Issue #1852
