That is not a bug.

zagzig% [[ x == y ]] && true
zagzig% echo $?
1

Hence { [[ $i == 2 ]] && exit 1; } is false, and { false || break } means
break.  The && expression is only true if -both- branches are true.

Further, { } is not a subshell, so { [[ 2 == 2 ]] && exit 1; } would most
likely produce something like
