PR56660 has been merged into release-8.5 accidentally #57465
Description
#56660 implemented an enhancement for better compatibility of MySQL, and it is already merged into release-8.5, which would be a LTS version.
Although it would not change the default behavior of authentication, if the variable default_authentication_plugin is set to a non-default value, it could affect the whole phase of authentication when using text-based auth plugins.
We have discovered a bug caused by this PR (see #57391). To guarantee the quality of LTS versions, this enhancement would be better if it appeared first in the next LTS after 8.5.
