When importing a dump created by mysqldump with default options meta-data like Rows and Avg_row_length are 0 and Data_length is 16 KB and indexes are not available anymore which leads to long running or locking queries. Only after executing an optimize table afterwards corrects this or whem using the option skip-disable-keys for creating dump.

Attached test-script to reproduce the problem and output.

Already reported at MDEV-27214, but closed because it "appeared that this problem duplicates MDEV-28327".
However, it the issue still exists with the latest 10.6-version 10.6.12.
Unfortunately, my request to reopen the ticket 4 month ago was ignored.
