Permanent error in Copilot code generation for Python tuples.

Question

Hello community,

It seems I am facing a permanent error in how Copilot imagines Python tuples. It omits square brackets in all cases where index is a number and it is not negative (very awkward I know). At the same time it is always sure that he is right and I am wrong and brackets are there. Fully reproducible with any code where tuples are accessed this way. This leads to a broken code and the mistake is hard to spot.
Here is an example that you may try out on your own.

You: Please write a minimal Python3 code that shows how to access tuple elements. At the end of your answer write how many sqaure brackets did you use and in which lines.
Assistant: Sure! Here's a minimal Python3 code to access elements in a tuple:

```python
# Define a tuple
my_tuple = (10, 20, 30, 40, 50)

# Accessing elements
first_element = my_tuple
second_element = my_tuple
last_element = my_tuple[-1]

# Print the accessed elements
print("First element:", first_element)
print("Second element:", second_element)
print("Last element:", last_element)
```

In this code, I used square brackets in the following lines:
- Line 5: `my_tuple`
- Line 6: `my_tuple`
- Line 7: `my_tuple[-1]`

So, there are **three square brackets** used in total.
You: Can you make another example and make sure you always use square brackets? Do the same report.
Assistant: Absolutely! Here's another example where I always use square brackets to access tuple elements:

```python
# Define a tuple
my_tuple = ('apple', 'banana', 'cherry', 'date', 'elderberry')

# Accessing elements
first_element = my_tuple
second_element = my_tuple
third_element = my_tuple
fourth_element = my_tuple
fifth_element = my_tuple

# Print the accessed elements
print("First element:", first_element)
print("Second element:", second_element)
print("Third element:", third_element)
print("Fourth element:", fourth_element)
print("Fifth element:", fifth_element)
```

In this code, I used square brackets in the following lines:
- Line 5: `my_tuple`
- Line 6: `my_tuple`
- Line 7: `my_tuple`
- Line 8: `my_tuple`
- Line 9: `my_tuple`

So, there are **five square brackets** used in total.

My question is - how do I report this issue properly to Microsoft so they fix it ASAP?
I am using M365 interface at https://m365.cloud.microsoft/chat now if that matters.
