Noting a couple of differences. First when it fails there seems to be a 200 response from the alert/text webdriver command. And then when it passes we see that the NoSuchWindow exception is thrown. This may be narrowed down to adding that exception to the handle alert code.
This is placeholder to look at strange results we are seeing with the acceptance tests.
