Symfony version(s) affected

5.4.25, 6.2.12, 6.3.1

Description

Upgrading symfony/validator from 5.4.34 to 5.4.35 breaks validation in a project of mine.
Some properties that have a NotBlank constraint applied are not detected as invalid when submitted without a value.
It seems that the regression was introduced in this change 6a3a4d7#diff-50c23a0a9ba92c8fb19fa501720ad061da508e3ccfd98fbcdfff2b7c8c6e6499 but unfortunately I cannot understand how.

How to reproduce

I'm sorry but it seems not so easy to provide a reproducer. In my project, I use XML validation and the problem appears on a property which is not directly defined in the validated object (it's defined in a parent object)

Possible Solution

Sorry, no clue about this

Additional Context

I isolated the problem during an upgrade, by requiring in my composer.json "symfony/validator": "^5.4,<5.4.25". With this requirement, all my tests pass.
If I replace it with the simple "symfony/validator": "^5.4", the tests break
