Logical Replication Sync - Issue with Table Bloat

Hello All,

I'm currently in the process of creating a logical replica of our
production database. Due to an oversight on my part in leaving archive_mode
= on, I had an issue in the middle of the process with disk space and had
to stop the database, clean up some stuff, and restart it. All the slots
reconnected fine with no issues.

But when I did this there was a slot doing the initial sync COPY command on
2 large tables which are together about 150GB in size. It was about 95%
done when I had to restart and by what I can tell, the COPY command had to
restart from scratch.

The problem is now that it's finished, when I look at the tables with
pg_relation_size(), the tables take up almost twice as much space on disk
(130 GB more than the publisher DB). Vacuum doesn't seem to have any effect
on reducing the size.

So my question is, should I be concerned about this? Will vacuum eventually
take care of this wasted space or is a VACUUM FULL my only option? (Running
VACUUM FULL also locks out the logical replication worker, which I'm
worried will run so long due to the table size that it will disconnect from
the replication slot on the publisher)

The output from VACUUM VERBOSE is attached if that helps:
