Cancelling tests in the "Debug Test" mode doesn't trigger pytest's fixtures teardowns (after yield).

[ivan-toriya-precis]

Type: Bug

Behaviour

Cancelling tests in the "Debug Test" mode doesn't trigger pytest's fixtures teardowns.

Is it an expected behavior or a bug?

Steps to reproduce:

1. Add a breakpoint after the fixture (with teardown using yield) is created.
2. "Testing" > "Debug Test"
3. "Cancel Tests"
4. Code after yield didn't run.

@ivan-toriya-precis This is expected. Cancel on the debug session sends a terminate request to the process.
