It depends entirely on how the template was invoked.
('match="headers/title"'; is a red herring; the template's
match expression doesn't affect the context node position
in any way.)

In this case, the template in question is invoked by
an <xsl:apply-templates/> instruction when the context node
is the 'headers' element.  <xsl:apply-templates/> is shorthand
for <xsl:apply-templates select="child::node()"/>, so the context
node list contains all the children of the <headers> element,
namely, an alternating sequence of text nodes (containing whitespace)
and <title> element nodes.

<xsl:strip-space elements="header"/> should give the expected answer,
as will <xsl:apply-templates select="child::title"/>.
