Can't import Temporal HIstorical data from backup

I can't seem to get my historical (temporal) data to import into a new instance of my database.

I've use `mariadb-dump` with the `-H` command to dump the history.
I see the columns `row_start` and `row_end` in the generated insert statements but not in the table create statements.

However, two things happen:

1. If I use the script as is an import the data the `row_start` and `row_end` times are the CURRENT date/time of the import and not what was in the file.

2. If I remove the `WITH SYSTEM_VERSIONING` in the generated script figuring we can't manually insert those values and I'll re-enable versioning after the import, when I try again the import fails because it can't find columns `row_start` and `row_end`

How are we supposed to backup and restore temporal tables?
