I don't understand test step "Open the frame in a new tab.". You mean the modal for selecting the field? How shall I do that?

Can you also change category_title to g.title to fix this:

Column not found: 1054 Unknown column 'category_title' in 'order clause'

Can you also change category_title to g.title to fix this:

Looks like we also need to take off category_title from here

Found another incongruity in backend Field modal when opening frame in new window. See Language at bottom of dropdown.

If I modify
https://github.com/joomla/joomla-cms/blob/staging/administrator/components/com_fields/views/fields/view.html.php#L207 to use a.language
and then in
https://github.com/joomla/joomla-cms/blob/staging/administrator/components/com_fields/views/fields/tmpl/modal.php#L60
same change.
I do get correctly

Let's solve also in this PR?

In the frontext test I see untranslated language strings in the pull down.
I don't think it is related to this PR, but have you both @Quy and @infograf768 applied any other fix which I haven't applied yet? I've fetched clean staging just right now and made a fresh, clean install, and patch I applied with patchtester.

[Quy]

Yes, you also have to install #25475 to fix the untranslated language strings which is not related to this PR.
