ZMI/portal_controlpanel/manage_editActionsForm brakes translations

[szakitibi]

BUG

GenericSetup controlpanel.xml allows configlets to be registered with translated titles (i18n:attributes="title"). This works in multilingual sites and Site Setup on classic UI show translated configlets.

However using ZMI/portal_controlpanel/manage_editActionsForm breaks translations here:

Products.CMFPlone/src/Products/CMFPlone/PloneControlPanel.py

Line 174 in 6212f6f

name = str(properties.get("name_%d" % index, ""))

The zope.i18n.message.Message is replaced with a plain str.

What I did:

Steps:

1. Registered a custom configlet with GenericSetup controlpanel.xml having a translated title using the products domain name (e.g. https://github.com/collective/pas.plugins.ldap/blob/main/src/pas/plugins/ldap/plonecontrolpanel/profiles/default/controlpanel.xml#L14).
2. Registered translations for the configlet title.
3. Used portal_controlpanel/manage_editActionsForm to make changes

What I expect to happen:

Translated titles keep working

What actually happened:

The i18n Message gets replaced with plain str translated, defaulting to plone domain - see here.

What version of Plone/ Addons I am using:

Plone 6.2.0
