Info breadcrumbs are currently implemented by inserting a string into
the Info buffer.  This breaks all point positions that Info functions
are relied upon.  It is a daunting task to try to account these offsets
for the lengths of breadcrumb strings inserted in all visited nodes
above the current node in the current Info file.  This practically
means rewriting the core logic of info.el just before the release.
