#name and ##keyword not working with rule annotations - annotations

Question

I'm trying to use ##keyword and #name in my grammar but tatsu seems to ignore it if rules tagged #name are annotated.
Am I missing something?
To reproduce the behaviour, I provide the following example:
This one works:
import tatsu
GRAMMAR = '''
##grammar::TestGrammar
##keyword :: if var
##whitespace :: /[\t ]+/
start =
var identifier ";" { var identifier ";" }* $
;
if = "if";
var = "var";
#name
identifier =
/[a-z]+/;
'''
if __name__ == '__main__':
import pprint
import json
from tatsu import parse
from tatsu.util import asjson
ast = parse(GRAMMAR, 'var xyz; var if;')
pprint.pprint(ast, indent=2, width=20)
As expected, tatsu will report
tatsu.exceptions.FailedParse: (1:16) "if" is a reserved word :
var xyz; var if;
^
If I annotate the identifier rule by
#name
identifier =
id:
/[a-z]+/;
the same python program will output
( 'var',
{'id': 'xyz'},
';',
[ [ 'var',
{'id': 'if'},
';']])

Basically, you should not define:
#name
identifier =
id:
/[a-z]+/;
TatSu will match the ast resulting from the rule against the names ##keyword, and the output of the above rule will always be {'id': 'something'}, which will not match any keyword.
Perhaps what you want is something like:
identifier = id:_identifier;
#name
_identifier = /[a-z]+/;
