Possible regression in support of setMethodS3() and setConstructorS3() of R.methodsS3 and R.oo

[Lucaweihs]

#525 added support for R.methodsS3::setMethodS3(name, class, definition) and R.oo::setConstructorS3(name, definition). With the newest version of Roxygen, attempting to run roxygen using these methods results in an

Error in methods::is(x, "refObjectGenerator") : object 'value' not found

error for me. I've created a minimal package demonstrating the error here. The error goes away when prepending the package namespace to setConstructorS3 and setMethodS3 (that is, always using the fully namespaced R.oo::setConstructorS3 and R.methodsS3::setMethodS3) but, when doing so, the s3 methods are not appropriately registered by the namespace (they are simply exported).
