Rails 8.1 misbehave using Mobility with ActiveModel `normalizes`

[pontflorian]

Environment

• Mobility version: 1.3.2
• Mobility backend: jsonb
• Rails version: 8.1.1
• Ruby version: 3.4.6
• Database: PostgreSQL

Description

It seems there is an issue using normalizes with Mobility in ActiveRecord since Rails 8.1.

# config/initializers/mobility.rb

Mobility.configure do
  plugins do
    backend :jsonb
    active_record
    reader
    writer
    backend_reader
    query
    cache
    column_fallback true
    fallbacks true
    presence
  end
end

# app/models/content.rb

class Content < ApplicationRecord
  extend Mobility

  normalizes :data, with: -> { it.compact_blank }

  translates :data, writer: false, column_fallback: false
end

Expected behavior

c = Content.new(data: { fr: "Non", en: "No", es: nil }) #  => <Content id: nil, data: {"fr" => "ok", "en" => "nope"}>
c.save # => true

Actual behavior

c = Content.new(data: { fr: "Non", en: "No", es: nil }) #  => <Content id: nil, data: {"fr" => "ok", "en" => "nope"}>
c.save # => undefined method 'compact_blank' for an instance of String (NoMethodError)

Error

normalizes method tries to execute a proc on a string (translated attribute) instead of the original column (Hash).
The same code works on Rails 8.0.
