Based on my knowledge of the pytest codebase and the issue description, I can generate the appropriate patch. The issue is in the `getstatementrange_ast()` function in `src/_pytest/_code/source.py`. In Python 3.8+, AST nodes have `end_lineno` attributes, but the function was using the start of the next statement to determine the end of the current statement. For decorated functions, the decorator's `@` symbol has a different line number than the function definition itself, causing the extra lines to be included.

Here is the patch:

Wait, I need to reconsider the actual fix. The issue is that when displaying the assertion error, pytest is including lines after the assert statement up to the next statement. In Python 3.9+, the `end_lineno` of a statement is available and should be used to determine where the statement ends, rather than looking at where the next statement begins.
|
|
|
|
Let me provide the correct patch based on the analysis:

Actually, I need to look at the actual logic more carefully. Based on the issue, the problem is in the statement range calculation. Let me provide a simpler, more targeted fix:
