+// TODO(v8::11388) Copying all data into a std::vector and then re-adding into

+// table, effectively changing the roles of full, empty and deleted buckets. It
+// then moves each entry to its new bucket by swapping entries (see
+// drop_deletes_without_resize in Abseil's raw_hash_set.h). This algorithm could
+// generally adapted to work on our insertion order preserving implementation,
+// too. However, it would require a mapping from hash table buckets back to
+// enumeration indices. This could either be be created in this function
+// (requiring a vector with Capacity() entries and a separate pass over the
+// enumeration table) or by creating this backwards mapping ahead of time and
