after list_remove item is still available

[ApaDoctor]

#include <stdlib.h>
#include "list.h"


int main(){
  list_t *gc = list_new();
  list_node_t *node =  list_append(gc, list_node_new("foo"));
  list_node_t *node_2 =  list_append(gc, list_node_new("bar"));
  printf("node: %s, node_2: %s\n", (char*)node->val, (char*)node_2->val);
  list_remove(gc, node);
  printf("length: %d\n", gc->len);
  printf("node: %s, node_2: %s\n", (char*)node->val, (char*)node_2->val);
  
  return 0;
}

Output:

node: foo, node_2: bar
length: 1
node: foo, node_2: bar

Is this a bug, or it's some compiler caching?

Is there a function called list_append in the implementation? I cannot see it. In test.c, list_rpush/list_lpush are used.
