Blueprint field of type: pages ignores multilingual route

[thekenshow]

I have a bilingual site, EN/FR; v1.7.37.1 (Admin v1.10.37.1). On that site, I have an FR page with the following frontmatter:

title: 'Signature Optica - Notre silence fait beaucoup de bruit'
published: true
routes:
    default: /nouvelles/signature-optica
    canonical: /nouvelles/signature-optica

I can browse to /fr/nouvelles/signature-optica and it displays as expected.

Next, I have a custom blueprint page with a type: pages field:

                    .buttonpagelink:
                      type: pages
                      size: medium
                      label: 'Choose a Web page on this site'
                      show_modular: false
                      show_root: true

When in the Admin, with FR selected, I choose the FR page Signature Optica - Notre silence fait beaucoup de bruit in the pick list:

I expected the resulting link to be /fr/nouvelles/signature-optica, but instead it applied the corresponding news/signature-optica-silence-making-big-noise EN path. Here's the frontmatter for the saved page:

       itembuttons:
            -
                buttonlabel: RENSEIGNEZ-VOUS
                buttonicon: null
                buttoniconloc: null
                buttonlink: null
                buttonpagelink: /news/signature-optica-silence-making-big-noise
                buttonweblink: null
                buttonclass: button
                buttontarget: _self
