Yes. It's been that way since bash-1.14. The reasons why are lost in
time -- it was 17 years ago, after all -- but probably go something like
not wanting the parent's settings to produce unexpected results in the
child process.
Current versions of bash disable -e inside command substitution only when
posix mode is not enabled.

Thanks, that's a problem.
