keycloak-ui Admin console "supported locales" dropdown doesn't show custom added language.

Describe the bug

By following Server Developer Guid, I added "zh-TW" (Traditional Chinese or 正體中文) to my custom theme.

The new language doesn't show up in dropdown menu.

I add "zh-TW" by directly access realm_supported_locales table in database.

And it come up in language selector.

Version

19.0.1

Expected behavior

Supported locales should show up custom add language.

Actual behavior

No response

How to Reproduce?

I use docker to run keycloak.

Anything else?

I also notice the "zh-CN" (Simplified Chinese or 简体中文) on "supported locales" dropdown shows "中文". Dose't match "中文简体" in origin resources properties.

Moving this issue to keycloak-ui repo.

@drsmile1001 Does the language show up if you switch to the old admin console?

To switch:

Go to Realm Settings --> Themes
Change Admin Console theme to keycloak

I tried to reproduce this but for me it does show up when I add the locale to the theme.properties locales: You right we no longer uses the display names in the resource bundle, but instead use the names that the browser uses. So for zh-TW that is 中文（台灣） and for zh-CH it's 中文（中国）

Yeah, although the functionality does not match what was there before I'd argue this solution is actually better as it relies on standardized APIs. I vote to close this issue.

@ssilvert @edewit @agagancarczyk WDYT?

I try pull latest docker image. Admin UI versiondd67b3b3a4e80031d32fdf0ffd9e9d450a657d07 It show 中文（中国） on Supported locales but zh-TW not 中文（台灣） But Default locale show 中文（台灣） And zh-TW option will disappear if unselect it.

Switch back to v1 theme. zh-TW will appear.
