Description:
We see the following description in the document https://dev.mysql.com/doc/refman/8.4/en/innodb-tablespace-autoextend-size.html.
If the tablespace is less than an extent in size, it is extended one page at a time.
I think this description is inaccurate. We can see in function fsp_reserve_free_extents that when the tablespace size is less than an extent in size, it is extended two pages at a time.

How to repeat:
This is a documentation issue.

Suggested fix:
I think this description is more reasonable.

If the tablespace size is less than an extent in size, it is extended two pages at a time.
