Other system tables have same problem?

It think so. In the PR here I moved the meta loaded event trigger after
processOfflineRegions, and modified CreateTableProcedure to always wait for
meta loaded so we will not create other system tables before
processOfflineRegions are done.
On branch-2 there is another problem that namespace table must be created
before meta table, so CreateTableProcedure need to check whether it is creating
namespace table, if so it should not wait for meta loaded event.
