      We hit an assert when processing consecutive tombstones, which I didn't expect to exist:

      /*
       * __hs_calculate_full_value --
       *     Calculate the full value of an update.
       */
      static inline int
      __hs_calculate_full_value(WT_SESSION_IMPL *session, WT_ITEM *full_value, WT_UPDATE *upd,
        const void *base_full_value, size_t size)
      {
          if (upd->type == WT_UPDATE_MODIFY) {
              WT_RET(__wt_buf_set(session, full_value, base_full_value, size));
              WT_RET(__wt_modify_apply_item(session, full_value, upd->data, false));
          } else {
              WT_ASSERT(session, upd->type == WT_UPDATE_STANDARD);
              full_value->data = upd->data;
              full_value->size = upd->size;
          }
      
          return (0);
      }
