As you know, for any bug fix, we try hard to provide the following:

  - test case
  - NEWS entry describing the problem and identifying affected releases
  - a commit log attributing the precise commit that introduced the bug

Can you provide at least a test case?

BTW, I still have not attributed the commit between 2.19 and 2.20
for the most recently described (in NEWS) bug fix.
