Bad Indentation Behavior of Rich-String with AFTER Clause

class Sample {
    def static void main(String[] args) {
        val a = #[1,3,5]
        val b = #[2,4,6]
        println('''
        demo:
            «FOR ax : a AFTER "\n"»
                call «ax»
            «ENDFOR»
            «FOR ax : b AFTER "\n"»
                call «ax»
            «ENDFOR»
        ''')
    }
}

results in

demo:
    call 1
    call 3
    call 5

        call 2
    call 4
    call 6

expected is

demo:
    call 1
    call 3
    call 5

    call 2
    call 4
    call 6

possible workaround

class Sample {
    def static void main(String[] args) {
        val a = #[1,3,5]
        val b = #[2,4,6]
        println('''
        demo:
            «FOR ax : a AFTER "\n"»
                call «ax»
            «ENDFOR»
            «FOR ax : b AFTER "\n"»
            	«""»
            	call «ax»
            «ENDFOR»
        ''')
    }
}

Start by reproducing the provided Sample rich-string example with two FOR clauses using AFTER "\n" and compare its output with the expected output. Trace the rich-string indentation handling for the second loop; done means both loop blocks retain the same four-space indentation without requiring the empty-string workaround.
