Fixes #717 The issue was that under Windows we generate text nodes that contained CRLF as a linebreak (rather than just LF as usual). The subtle problem is that when these strings are placed in the DOM via createTextNode(), the CR character is treated as a printable character, not whitespace. When creating DOM notes with innerHTML or as part of a static HTML document the HTML parser will strip out the CR characters. The hacky solution is to manually remove CRs before building the text node.
