XSLTRANSFORM issue with WELLFORMED xml documents

Issue

• XSLTRANSFORM doesn't work or return result with newline character. For example, below returns NULL due to new line character \n

select XSLTRANSFORM('<?xml version="1.0" encoding="utf-8"?>\n<a><b/></a>', '<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"><xsl:template match="/"><xsl:copy-of select="/"/></xsl:template></xsl:stylesheet>')

• Below returns result correctly.

select XSLTRANSFORM('<?xml version="1.0" encoding="utf-8"?><a><b/></a>', '<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"><xsl:template match="/"><xsl:copy-of select="/"/></xsl:template></xsl:stylesheet>')
