Semantic highlighting fails to recognize method

[D4n16l6]

Type: Bug

I used Developer: Inspect Editor Tokens and Scopes to inspect this code (complete code is very long):

                self.signal_history_orderbook.append(combined_signal)
                if len(self.signal_history_orderbook) > self.signal_history_max_size:
                    self.signal_history_orderbook.pop(0)

                self.signal_history_counter += 1
                if self.signal_history_counter % 5 == 0:
                    # Calcola percentuali degli ultimi segnali
                    total_signals = len(self.signal_history_orderbook)
                    hold_count = self.signal_history_orderbook.count('hold')
                    buy_count = self.signal_history_orderbook.count('buy') 
                    sell_count = self.signal_history_orderbook.count('sell')

and the result is:

METHOD POP :

pop3 chars
language	python
standard token type	Other
foreground	#AA3731
background	#F5F5F5
contrast ratio	5.84
font style	bold
semantic token type	method
modifiers	builtin
foreground, bold, italic, underline, strikethrough	entity.name.function.member
entity.name.function
support.function
{ "fontStyle": "bold", "foreground": "#AA3731" }

METHOD COUNT :

count5 chars
language	python
standard token type	Other
foreground	#333333
background	#F5F5F5
contrast ratio	11.59
textmate scopes	meta.function-call.generic.python
meta.function-call.python
meta.member.access.python
source.python

METHOD APPEND:

append6 chars
language	python
standard token type	Other
foreground	#333333
background	#F5F5F5
contrast ratio	11.59
textmate scopes	meta.function-call.generic.python
meta.function-call.python
meta.member.access.python
source.python
foreground	No theme selector

Only POP is colorized ad method APPEND and COUNT not but not exception in execution.
