different indent when pass environment variables with command substitution

[chnkd]

foo=foo \
    echo foo

foo=$() \
    echo foo

foo=foo \
    bar=bar \
    echo foobar

foo=$() \
bar=bar \
    echo foobar

Sorry but I don't understand. Exactly what did you run and what happened?

[chnkd]

Assign a constant to foo, the code will be formatted as below:

foo=foo \
    bar=bar \
    echo foo bar

Replace with command substitution, and the indent style of formatted code is different from the above

foo=$(echo foo) \
bar=bar \
    echo foo bar

Thanks, that does look like a bug.
