Symfony version(s) affected

v6.2.0-BETA2

Description

In Symfony v6.2.0-BETA2, I'm unable to use the YAML !php/const: prefix in doctrine config

Previously, you could do this:

doctrine:
    dbal:
        options:
            !php/const:PDO::MYSQL_ATTR_INIT_COMMAND: SET max_execution_time=60000

In Symfony v6.2.0-BETA2, I get the following error:
Invalid type for path "doctrine.dbal.connections.default.options". Expected "array", but got "Symfony\Component\Yaml\Tag\TaggedValue"

Although there's a simple workaround I wonder if it doesn't affect configuration in other places/cases, which is why I report it

How to reproduce

Add the following config in doctrine.yaml:

doctrine:
    dbal:
        options:
            !php/const:PDO::MYSQL_ATTR_INIT_COMMAND: SET max_execution_time=60000

In Symfony v6.2.0-BETA2, I get the following error:
Invalid type for path "doctrine.dbal.connections.default.options". Expected "array", but got "Symfony\Component\Yaml\Tag\TaggedValue"

Workaround is to use the constant value instead

doctrine:
    dbal:
        options:
            1002: SET max_execution_time=60000
