The "local" command has its own exit status, and this masks the exit
status of the command substitution.

Just continue using that.  This isn't a bug in bash, and it won't be
changed.

(While you're at it, you might want to switch from the obsolete backtick
syntax to the preferred $() syntax for command substitutions.)
