Good catch. The change you mentioned above made libxslt actually do the wrong 
thing and strip the text node. The relevant code is here:

https://git.gnome.org/browse/libxslt/tree/libxslt/xslt.c?id=683cbc82dee4cea75822a0f7cafd97768b6165ff#n3556

xmlNodeGetSpacePreserve is called with a text node and consequently returns -1 
after the change. The relevant commit to libxml2 is "Adding various checks on 
node type though the API":

https://git.gnome.org/browse/libxml2/commit/?id=3e62adbe39f2083c9c2cd3330c320227818fd361

This commit first appears in libxml2 version 2.9.0. I just committed a fix to 
libxslt to adjust for this change:
