I can reproduce the OP's result with the system bash but not with 5.1
or 5.1 patch 4.


% /bin/bash --version | head -n 1
GNU bash, version 3.2.57(1)-release (x86_64-apple-darwin18)
% /bin/bash -c 'od -bc <<< $(echo -e "foo\nbar")'
0000000   146 157 157 040 142 141 162 012
           f   o   o       b   a   r  \n

% work/destroot/opt/local/bin/bash --version | head -n 1
GNU bash, version 5.1.0(1)-release (x86_64-apple-darwin18.7.0)
% work/destroot/opt/local/bin/bash -c 'od -bc <<< $(echo -e "foo\nbar")'
0000000   146 157 157 012 142 141 162 012
           f   o   o  \n   b   a   r  \n

% bash --version | head -n 1
GNU bash, version 5.1.4(1)-release (x86_64-apple-darwin18.7.0)
% bash -c 'od -bc <<< $(echo -e "foo\nbar")'
0000000   146 157 157 012 142 141 162 012
           f   o   o  \n   b   a   r  \n
