syntax: End brace of grouping expression not indented when part of multicommand && chain

[reteps]

I have this formatted snippet produced by shfmt:

command \
    && command2 && {
    echo "This is grouped"
} \
    && command3

I would expect this to indent the grouped expression an extra level in this scenario:

command \
    && command2 && {
        echo "This is grouped"
    } \
    && command3

Alternately:

command \
    && command2 && {
    echo "This is grouped"
    } \
    && command3

It feels unexpected to me that the curly brace } is not indented in this scenario.

I noticed a similar issue in this scenario:

apt update \
    && apt install -y curl \
        git \
        pandoc \
        sqlite3 \
        sudo \
    && install.r bench \ 
data.table \
    devtools
