Thanks for the report and the reproducer.
This bisects to c1aed9f80 (ob-core: Refactor
`org-babel-expand-noweb-references', 2020-01-12). The patch below
addresses the case you provided (added as a test) and doesn't cause any
of the other tests to fail. However, I'm no tangler, so I'd appreciate
if you could give it some testing and report back.
(I should also look more closely at org-babel-expand-noweb-references
before applying and see if I spot anything that suggests this change is
problematic.)

Subject: [PATCH] ob-core: Fix handling of multiple noweb refs in same line
* lisp/ob-core.el (org-babel-expand-noweb-references): Don't anchor
noweb regexp at start of line to allow multiple matches per line.
* testing/lisp/test-ob-tangle.el (ob-tangle/multiple-noweb-in-line):
Add test.
This fixes a regression introduced by c1aed9f80 (ob-core: Refactor
`org-babel-expand-noweb-references', 2020-01-12), which was part of
the 9.4 release.
