Regression appears to have occurred between bash-5.0.18 and bash-5.1-alpha at commit 712f80b0. (I note that this commit is missing from the master branch, which only includes bash-5.0.17 at commit.) I tried to find the change in the devel branch, but ugh, git diff between devel & master is unhelpful.
