Description
We have been utilizing Saxon-HE jars in our product for XSLT use cases.
Recently, we upgraded the Saxon version used in our products from 9.5.1-8 to 10.8. Following this upgrade, one of our customers encountered an issue, which is documented in [1]. Despite the issue description indicating that it was resolved in maintenance versions 9.9.1.8 and 10.3, we are still observing the issue in version 12.4.
I am providing a sample java project to reproduce the issue. If we change the dependency to 9.5.1-8 dependency, we get the correct output without namespaces. else we get the output with namespaces.

copy-namespaces="no" helps to ensure in-scope but unused namespaces are not copied, it doesn't remove the namespace an element itself is in. So the result you get from 12.4 is the correct one.

Martin is correct: the effect of copy-namespaces="no" is to drop unused namespace declarations, it should never move an existing element into a different namespace.
That raises the question of why it behaved differently in Saxon 9.5. Unfortunately investigating a very old release like that isn't easy.
I have confirmed that the output changed (that is, the bug was fixed) between 9.5.1.8 and 9.5.1.10, that is, between January and May 2015.
I think the most likely explanation is that the change in behaviour was caused by fixing bug #2209.
