I had a quick look, and yes, it's the grammar. Around line 367 this pattern, that I don't claim to understand the purpose of, gobbles up ()

{   begin = '(()';     end = '())';     patterns = ( { include = '$self'; } ); },

before the pattern matching tuples around line 392 get a chance to process it

{   name = 'meta.structure.tuple.python';     match = '(()(\s*()))';     captures = {         1 = { name = 'punctuation.definition.tuple.begin.python'; };         2 = { name = 'meta.empty-tuple.python'; };         3 = { name = 'punctuation.definition.tuple.end.python'; };     }; },

so, effectively, tuples aren't recognized by the grammar.

I deleted the first entry and got expansion of () working without any obvious destructive side-effects. YMMV.
