Combined tids in parent term url break breadcrumbs- sort of

When a parent term url is combined with child term and sub term tids (taxonomy/term/10+11+12 where 10 is the parent term), it displays the system url (taxonomy/term/tid) of the parent term in the browser status bar when the mouse is hovered over it in the breadcrumb trail.

This seems to affect only the parent term.

Here are a couple of examples:
http://www.ciosa.org.in/beta/cop/child-care (hover on the parent term 'CoP' in the breadcrumb trail)
http://www.ciosa.org.in/beta/events/member-events (hover on the parent term 'events' in the bc trail)

Would be great if TC displayed the parent term name even when the tids are combined.
