There was a problem hiding this comment.
Just a quick inline comment, I also think we should have some expansion of the test coverage here, places like: https://github.com/Qiskit/qiskit-terra/blob/main/test/python/compiler/test_transpiler.py#L1762, https://github.com/Qiskit/qiskit-terra/blob/main/test/python/compiler/test_transpiler.py#L1784, https://github.com/Qiskit/qiskit-terra/blob/main/test/python/compiler/test_transpiler.py#L1821, and https://github.com/Qiskit/qiskit-terra/blob/main/test/python/compiler/test_transpiler.py#L1531 would be simple enough to update the ddt decorator. But there are probably a few other control flow tests we should parameterize on multiple optimization levels with this PR.

In CI we're seeing a reliable failure on windows when scipy is calling LAPACK. This appears to be unrelated to the change in this PR branch and is isolated to specific windows environments. This commit adds a skip condition to skip that one test to workaround the failure in CI. The wider issue with scipy compatibility on windows is being tracked in issue Qiskit#10345, when we have a conclusion to that and can reliably run this test we should remove this skip condition.
