I have added a top-up patch v30-0003. The issue in [1] still exists in
the v30 patch. I was not able to come up with an approach to handle it
in the code, so I have added it to the documentation in the warning
section. Thoughts?
I am not changing the version as I have not made any changes in
v30-0001 and v30-0002.
Thanks and regards,
Shlok Kyal
