Encrypted fields in EntityQuery as a condition

Problem/Motivation

Nodes use encrypted fields (via field_encrypt). After encryption is enabled, the
original field value is no longer stored in plaintext in the database and is
replaced by an encrypted placeholder (🔒).
As a result, entity queries that rely on these fields can no longer filter results, because the stored value is not
queryable.

Steps to reproduce

1. Create a content type with a field.
2. Enable encryption for this field using the field_encrypt module.
3. Save content with a value in the encrypted field.
4. Run an entity query with a condition on the encrypted field.
5. Observe that the query returns no results, because the stored value is replaced by an encrypted marker (🔒).

$nodeId = \Drupal::entityQuery('node')
->accessCheck(FALSE)
->condition('type','article')
->condition('field_custom_value', 'My value')
->execute();

Am I missing anything? Is it possible to somehow query the node using the encrypted fields as the query condition?
