🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Return the receiver through object_handle, not the stale object local.

object is captured at Line 9 and is a raw local. Before this branch runs, two GC-capable calls execute: js_object_get_own_field_or_undef at Line 465 and call_primitive_closure_value at Line 467, which can run a user valueOf. A moving collection there relocates a pointer-bearing receiver.

!jsval.is_pointer() is true for heap strings and BigInts, which carry a heap address in their payload. For "x".valueOf() or (5n).valueOf(), the branch then returns a stale address. The hasOwnProperty and propertyIsEnumerable arms in this same function already re-read the receiver through object_handle for this exact reason (#6935 / #6943).

The tag view itself is stable, so jsval.is_pointer() stays correct; only the returned payload needs the refresh.

🔒️ Proposed fix
             if !jsval.is_pointer() {
-                return Some(object);
+                return Some(object_handle.get_nanbox_f64());
             }
-            return Some(js_object_default_value_of(object));
+            return Some(js_object_default_value_of(object_handle.get_nanbox_f64()));

This follows the guideline "A GC-managed value's root store must dominate every subsequent site that can collect".

lines 475 - 483, In the primitive-wrapper branch of the common-method handler,
return the receiver re-read from object_handle rather than the stale object
local after the GC-capable calls. Preserve the existing jsval.is_pointer() check
and js_object_default_value_of behavior for pointer values, while ensuring heap
strings and BigInts return the refreshed rooted value.
