Sections field on media doesn't respect workbench access limitations in the media widget version of form

[kevwalsh]

Describe the defect

As Austin.wilmarth@va.gov, sections field on media allows me to add media to any section at VA. I should only see Colorado Springs

To Reproduce Steps to reproduce the behavior:

1. Log in as Austin.wilmarth@va.gov
2. Go to /media/add/image
3. See that you only have access to one section (which should be pre-populated, but is not)
4. Go to https://staging.cms.va.gov/node/3792/edit and add a photo (upload from your computer)
5. Note the Sections field shows _all_sections.

Expected behavior

I should only see the section i have access to (Colorado Springs Vet Center), like i do on the /media/add/image form. Ideally, if i only have access to one section, it should be prepopulated

Screenshots

Current behavior on media widget version of image form

Comparison of two widgets, between the media widget (top) and /media/add/image (below)

Vet Center Service form

ACs

• [ ] Members of a section can only add media to their section in the media widget
• [ ] Members who only have one section have that section prepopulate in media widget or /media/image/add
• [ ] Editors of Vet Centers can only select their section (and it's preselected) on the IEF for Services on Vet Center forms
• [ ] On edit, options are not changed

CMS Team

Please leave only the team that will do this work selected. If you're not sure, it's fine to leave both selected.

• [ ] Core Application Team
• [x] Product Support Team

Per our scrum convo on 6/3, approach should be to resolve workbench bug that is preventing modal from being aware of current context. E.g.: don't extend the js approach used to winnow health service dropdowns.

Gonna have to abandon the non-js approach for this one for now - stepping through it in the debugger is yielding no clues. I can't figure out where the magic is that is limiting results when the "default" entity reference method is selected, here: /admin/structure/media/manage/image/fields/media.image.field_owner - I tried creating a new entity reference view, but this requires a new term view, with a reference to be made to the node lock user, and this relationship doesn't connect to the user section list. @kevwalsh

I found this without the team label on it. Adding to our backlog @productmike @BerniXiongA6
