This issue was initially reported by @michaelgranzow-avi on #2296. @airween made an initial attempt to provide a fixed at #2107; As a consequence of the pull request review - provided by @victorhora, @zimmerle, and @michaelgranzow-avi - @airween made a second attempt at #2297. After reviewing by @martinhsv, @zimmerle, I have absorbed the essential pieces from @airween patch into this one. This patch differs from @airween's because @airween's patches were partially working: Key exclusions with regex weren't covered, same for anchored variables (e.g. ARGS). During the review, I have highlighted the importance of having elementary test cases. A simple test case on ARGS could spot the issue. Since that is an important fix, I don't want to hold this for one more review cycle; therefore, I am committing the fix myself. Thank you all involved in the solution of this very own issue.
