babel/noweb concatenation of equally-named code blocks fails?

[Greg Minshall <minshall@umich.edu>]

hi.  the description of :noweb-ref says
----
When expanding “noweb” style references, the bodies of all code block
with _either_ a block name matching the reference name _or_ a
‘:noweb-ref’ header argument matching the reference name will be
concatenated together to form the replacement text.
----
plus, this (admittedly old) page suggests this concatenation should
happen:

----

if i evaluate (C-c C-c) "tryxx" below on the 9.1.9 which is in my emacs
(26.3), i get two lines of output (as shown).  if, using packages, i
"upgrade" to either of the following:
----
  org                9.3.6         available  gnu
  org                20200413      available  org
----
(and, also a 201912...), i only get the first output line ("in first
tryx").  (*tangling*, i get both code blocks.)

is the behavior in the newer versions intentional?  or, should i file a
bug?

cheers, and thanks.  and, these days, stay safe.  Greg
