When bold (or italic) text is separated from italic (or bold) text by a space and the editor selects that space when converting the first block to bold italic in VE, then Parsoid adds the markup around the selected block, replaces the space with a <nowiki/> and then adds a space between the starting bold/italic markup and the text for the second section.

In other cases with bold italic adjacent to italic it generates
'''''bold itlaic''''''' italic''
which renders the bold italic text as bold italic followed by '' and the italic text as plain. 

Desirable markup:
'''''bold italic''' italic''
