Looks like it is working as designed.  

probe process ("libfoo.so").library("libfoo.so").function(0x55e).call 
 maps to and seems to behave identical to:
probe process ("libfoo.so").function(0x55e).call

query_addr has this check.
          if ((tag == DW_TAG_subprogram && !q->has_inline) ||
              (tag == DW_TAG_inlined_subroutine &&
               !q->has_call && !q->has_return))
which in the above case is checking
tag == DW_TAG_inlined_subroutine
q->has_call == true

and thus it fails.

For the case where a probe is added to libfoofunc then the check becomes
tag == DW_TAG_subprogram
q->has_inline == true
