Can move the code to config.after_initialize or inside ActiveSupport.on_load(:action_text_content)

Switching config.load_defaults to 7.1 switches from Rails::HTML4::SafeListSanitizer to the new Rails::HTML5::SafeListSanitizer which doesn't seem to pickup these changes in the initializer

Thanks, that worked. I added this test to my project to verify and handle any future changes

require "test_helper"

class ActionTextCustomizationTest < ActiveSupport::TestCase
  test 'action text links should have rel="noopener noreferrer" and target="_blank"' do
    text = ActionText::RichText.new(
      body: "<a href='https://example.com'>Example</a>"
    )

    assert_includes text.to_s, "rel=\"noopener noreferrer\""
    assert_includes text.to_s, "target=\"_blank\""
  end
end

ActionText::ContentHelper.allowed_attributes dont seem to be working in Rails 7.1 due to some changes to the sanitizer

Hey! Sorry this is probably too late to help in your case but you can override the: attachable_plain_text_representation(caption) method on your ActionText::Attachable model. By default this method uses the caption (for images) but since we aren't setting a caption for @-mentions, the text is blank if you call to_plain_text.

In this example, you might override the method to return something like "@#{name}" for the plain text formatting.
