I do not have a test for this as it's too hard to test for. We require the following scenario to happen:
We don't have that many non-progressing specializations to begin with, so any test is a futile fight between the internal implementation details and the JIT.
I have verified this fixes the test case in the issue. I'm not using the test case in the issue as it's dependent on how much stack space we reserve and consume per stack chunk. If we ever change the stack chunks size, the test will break.
