To fix this one idea is to remove the breadcrumbs line on leaving
from the node, so breadcrumbs in all nodes located above the current
node will not affect the point position.  And in the case of getting
the current point position, subtract the length of breadcrumbs in
the current node.

This part of the bug report is fixed now.
