Found a gotcha with the interactive parser

[RevanthRameshkumar]

parser = Lark(r"""
%ignore /[\t \f]+/  // WS

start: d|c
d: B
c: A B
A: "abc"
B: /[^\W\d]\w*/
""", parser="lalr")


input_str = 'abc'
interactive = parser.parse_interactive(input_str)
print(interactive.exhaust_lexer())
interactive.accepts()

The output is

[Token('A', 'abc')]
{'B'}

but if you modify the input str with a B token, then the output turns into:

[Token('B', 'abcfdsfds')]
{'$END'}

Is there a way to recognize that we need a whitespace separated B token and not just an immediate B?
