So this is a workaround only for the current implementation of Kint and Faker? If so, why do we mask all instances, not just those coming from these libraries?

[kenjis]

Thanks. I added code to check if it is caused by Faker or Kint.

[michalsn]

Thanks!

Hopefully these libraries will be updated before the release of PHP 8.4.
