xbstream creates non-sparse ibd files and breaks COMPRESSION='zlib'

Backup source: Percona Server 5.7.19-17, xtrabackup version 2.4.9
Backup destination: xtrabackup version 2.4.12 (used for xbstream and prepare)

xtrabackup --binlog-info=ON --use-memory=5000M --target-dir=/tmp --backup --lock-ddl --lock-ddl-timeout=300 --parallel=2 --stream=xbstream | nc 10.0.1.5 3355 # on backup source

1. on backup destination
   nc -l 3355 | xbstream -x -C /var/lib/mysql1
   xtrabackup --prepare --target-dir /var/lib/mysql1

#on backup source
du -h /var/lib/mysql/test/t.ibd
6.3G /var/lib/mysql/test/t.ibd
ls -lh
rw-r---- 1 mysql mysql 14G Jul 5 03:01 t.ibd

#on backup destination
du -h /var/lib/mysql1/test/t.ibd
14G /var/lib/mysql1/test/t.ibd
ls -lh t.ibd
rw-r---- 1 mysql mysql 14G Jul  5 06:48 t.ibd
cp -a --sparse=always t.ibd t.ibd.sparse
du -h /var/lib/mysql1/test/t.ibd.sparse
12G /var/lib/mysql1/test/t.ibd.sparse

After table rebuild with alter table t ALGORITHM=COPY;
du -h t.ibd
3.6G t.ibd
du -h t.ibd --apparent-size
9.1G t.ibd

if I'm using rsync for original file 6.3G file (located on backup source):
rsync --sparse t.ibd /
du -h /t.ibd
4.6G /t.ibd
du --apparent-size -h /t.ibd
14G t.ibd

Also rsync --sparse works fine with altered file 3.6G (located on backup destination):
du -h t.ibd
2.5G t.ibd
du --apparent-size -h t.ibd
9.1G t.ibd
