BulkInsertAsync does not seem to want to insert entries where the entry has a child entity that is null

[snydesc]

Given a model that looks like:

public class EntryA
{
   [Key]
   public int EntryAId { get; set; }

   public string? EntryBId { get; set; }
   
   [ForeignKey(nameof(EntryBId ))]
   public virtual EntryB? EntryB{ get; set; }
}
public class EntryB
{
   [Key]
   public string EntryBId { get; set; }
}

and then trying to insert the following

EntryA entryA = new EntryA()
{
   EntryAId = 1
}
List<EntryA> listOfEntryA = new List<EntryA>();
listOfEntryA.Add(entryA);

await context.BulkInsertOrUpdateAsync(listOfEntryA);
await context.BulkSaveChangesAsync();

will not throw any errors, but will not insert the entry.
If you populate EntryA.EntryBId with a valid id for a record in the EntryB table then it will get inserted.

making the same call with EFCore AddRangeAsync works fine
.
This is being inserted into a SQLite database.
