On Mac and Linux, all but two of the newly added region tests pass (RT-33446 is tracking those two failures).

However, on Windows, 48 tests fail, many of them timeout after 5 seconds and many others fail with an assertion failure.

Here is a list of the failing tests (the first two are due to RT-33446). The complete log file is attached.
