      Description

      A spinoff from LUCENE-8381. If a soft-deletes docvalues was applied to PendingSoftDeletes already, newDelCount should be less than the softDelCount recorded in SegmentInfo. The attached test trips an assertion in PendingSoftDeletes. I think we need to relax that assertion.

       

      java.lang.AssertionError: softDeleteCount doesn't match 1 != 0
