Unrecoverable timeouts when WAITFOR DELAY occurs anywhere. Poison pill

[cburhob01]

Describe the bug

Copilot will enter into a faulted state anytime the text 'WAITFOR DELAY' is encountered, either within the prompt or when copilot reads a file. With ANY model.

To test, Try with this prompt:
Explain what WAITFOR DELAY does in MSSQL.

Result:
● Request failed due to a transient API error. Retrying...

● Request failed due to a transient API error. Retrying...

● Request failed due to a transient API error. Retrying...

● Request failed due to a transient API error. Retrying...

● Request failed due to a transient API error. Retrying...

✗ Execution failed: Error: Failed to get response from the AI model; retried 5 times (total retry wait time: 6.00 seconds) Last error: CAPIError: Connection error. 

The context becomes unrecoverable and the only fix is /new.

Also try putting that text inside a file. I tested with a C# file and added that text as a comment and asked copilot to explain the file.

Here is the file:
using System;

class Program
{
     -- Main function WAITFOR DELAY
    static void Main()
    {
        Console.WriteLine("Hello, World!");
    }
}

Explain @Test.Api\Program.cs

◐ I need to look at the Program.cs file from the Test.Api project to understand what it does.

● Read Program.cs
  │ Test.Api\Program.cs
  └ 11 lines read

● Request failed due to a transient API error. Retrying...

● Request failed due to a transient API error. Retrying...

● Request failed due to a transient API error. Retrying...

● Request failed due to a transient API error. Retrying...

● Request failed due to a transient API error. Retrying...

✗ Execution failed: Error: Failed to get response from the AI model; retried 5 times (total retry wait time: 6.00 seconds) Last error: CAPIError: Connection error. 

If I remove the comment, the correct hello world explanation is returned.

To me this is a critical bug because this poison pill could be injected into any file effectively crippling copilot as it ingests files to build its context.
