Nhat Nguyen updated LUCENE-8381:
--------------------------------
    Description: If a document is soft-deleted, then hard-deleted, IW, however, 
accounts that document as soft-deleted when wrapping readers for merges.  (was: 
The current PendingSoftDeletes#onNewReader does not handle these two edge cases 
correctly.
 # If the soft-deletes DV was applied to PendingSoftDeletes already, 
newDelCount should be less than the soft delete count recorded in SegmentInfo. 
testSoftDeleteWithTryUpdateDocValue trips the newSoftDelCount assertion.
 # If the soft-deleted docs were hard-deleted, we should reduce the 
softDelCount in the segmentInfo on a new reader.)
