Denser Blog fails to broadcast comment_operation when permlink contains dot

Denser Blog fails to broadcast comment_operation when permlink contains dot. That failing permlink is produced by Blog itself, I suppose. To duplicate the issue try to reply to comment /hive-106130/@missbitcoin-sv/vvvvrnjste#@meme.bot/re-sewt1f-20240611t093506z

The error was returned by API on hive-5.pl.syncad.com (API on api.hive.blog fails, too). See screenshot from Denser Blog app:

Failed transaction was:
