Bug: org-babel only tangles first noweb reference on a line [9.4 (9.4-elpaplus @ /home/tom/.emacs.d/elpa/org-plus-contrib-20200914/)]

[Tom Gillespie]

Hi,
   The 9.4 release has a bug where it will only tangle the first noweb
reference on a line.
This is also present at 9c31cba002a1ba93053aebea1f778be87f61ba06. It happens in
emacs-27 and emacs-28. The reproduction is below. Best!
Tom

The expected content of oops-3.el should be 1 2 1, but is instead 1
<<block2>> <<block1>>.
C-c C-v C-t or C-c C-v C-v will show the issue.

#+name: block1
#+begin_src elisp
1
#+end_src

#+name: block2
#+begin_src elisp
2
#+end_src

#+name: block3
#+begin_src elisp :noweb yes :tangle ./oops-3.el
<<block1>> <<block2>> <<block1>>
#+end_src
