*slime-inspector* [set value] and current package not in synch

[mon_key]

From the *slime-inspector* window, with the *slime-inspector* as
current-buffer when I evaluate the elisp form:
 (slime-interactive-eval *package*)
the return value is a package descriptor for PKG-A.

When inspecting a class instance INSTANCE-I interned in package PKG-A I'm
given the option of setting the slot value for SLOT-S of INSTANCE-I.

This option is presented as a button "[set value]" in the *slime-inspector*.
The elisp command `slime-inspector-operate-on-point' is attached to the button.

SLOT-S of INSTANCE-I has neither :reader :writer nor :accessor methods,
e.g. it its spec is:
 (slot-s :initarg slot-s :initform nil)

When attempting to set SLOT-S of INSTANCE-I from *slime-inspector* to the
value of a defvar'd variable PKG-A:VAR-V interned in package PKG-A as VAR-V, I
get the warning that:

 "The variable COMMON-LISP-USER::<VAR-V> is unbound."

If instead I set the slot value to the value of PKG-A:VAR-V it works fine.

When invoking the "[set value]" action from the *slime-inspector* buffer why
does it not recognize that the current package is PKG-A and not
COMMON-LISP-USER?
