It seems that this might actually be a feature.
Quoting the COMPAT document of bash4:
38. Since bash-4.0 now follows Posix rules for finding the closing delimiter
of a $() command substitution, it will not behave as previous versions
did, but will catch more syntax and parsing errors before spawning a
subshell to evaluate the command substitution.
Ciao,
