Steps to Reproduce

1. Have an extension class
2. Define a generic extension method where the this parameter is a generic type parameter from the extension method
3. Assign constraints to the generic type parameter that is the extension
4. Attempt to invoke the generic extension method on a value satisfying the constraints
5. Observe the IntelliSense suggestions

A relatively long code snippet is found on SharpLab, showing multiple cases of failing to suggest valid extensions. Try typing the names of the extensions anew to notice the lack of the suggestion.

Expected Behavior

All generic extension methods that have their generic type parameter constraints met are recommended.

Actual Behavior

Only unconstrained generic methods are recommended. When a desired generic extension method is manually typed, it is properly recognized and no error is reported.
