test-ttywrap.writestream.js test always passes #28304

• Version: v13.0.0-pre
• Platform: macOS Mojave
• Subsystem: test, async-hooks

In test/async-hooks/test-ttywrap.writestream.js, there is delayedOnCloseHandler() which is supposed to check the async-hooks graph. When I run directly with the node executable, the test fails. When run with tools/test.py, though, the test passes. On my computer, at least, I can change the contents of delayedOnCloseHandler() to anything. It can just be a throw statement. The test will fail as expected when run directly with node but will pass when run with tools/test.py.

First, can someone else confirm this so that we can label this with confirmed-bug (or find that they don't experience this behavior in which case I can look more closely at exactly what I'm doing wrong).

Second, does anyone know why this would be the case?
