My dash is 0.5.12 as well. I suspect it was a series of unfortunate
events - on occasion, I change my /bin/sh back to Bash temporarily to
confirm/deny a bug is related, and I sometimes forget to change it back

Someone reported https://bugs.gentoo.org/738826 in 2020 at least which
I didn't spot until now, so I think you're right that this isn't new at
all, and just nobody noticed it until now.
