tangling indentation broken when using tabs

[goyalyashpal]

mwe:

0. spaces (correct)

input (spaces)

@o src/attempt.py @{
@< att load data @>
@}

@d data schema@{
data_schema = sml.Seq(
    sml.Map({
        "ques": sml.Str(),
    })
)
@}

@d att load data @{
def load_data():
    @< data schema @>
@}

output (spaces)

def load_data():
        
    data_schema = sml.Seq(
        sml.Map({
            "ques": sml.Str(),
        })
    )

faulty ones

1. with tabs:

input (tabs):

@o test.py @{
@< att load data @>
@}

@d data schema@{
data_schema = sml.Seq(
	sml.Map({
		"ques": sml.Str(),
	})
)
@}

@d att load data @{
def load_data():
	@< data schema @>
@}

output (tabs):

notice the space before def

def load_data():
	 
 data_schema = sml.Seq(
 	sml.Map({
 		"ques": sml.Str(),
 	})
 )

Others too (with tabs):

2. -indent

@o test.py @{
@< att load data @>
@}

@d -indent data schema@{
data_schema = sml.Seq(
	sml.Map({
		"ques": sml.Str(),
	})
)
@}

@d att load data @{
def load_data():
	@< data schema @>
@}

notice the space before data_scheme & its corresponding closing parenthesis ) at same indentation

def load_data():
	 
 data_schema = sml.Seq(
 	sml.Map({
 		"ques": sml.Str(),
 	})
 )

3. -noindent

@o test.py @{
@< att load data @>
@}

@d -noindent data schema@{
data_schema = sml.Seq(
	sml.Map({
		"ques": sml.Str(),
	})
)
@}

@d att load data @{
def load_data():
	@< data schema @>
@}
