The Supervisor part of the front end does not honor the selected theme, it's using the default theme to render.
Supervisor should be rendered with the same theme as the rest of the front-end
Navigate to main dashboard - observe theme
Navigate to Supervisor section- observe selected theme is not honored


What version of the supervisor is this?

The console output contains nothing
There is no reason that should not work.

This is the same versions (mostly)
Try another theme, I used this one to test https://github.com/aFFekopp/noctis
I have an automation on startup that sets the theme to blue-night, so my user theme is set to Backend-selected. this renders incorrectly in Supervisor. If I fire the automation again to set the theme, no change. If I change my user theme to blue-night instead of Backend-selected, it displays correctly.
I installed noctis, restarted homeassistant and it also does not render on the supervisor page unless I set my user theme to noctis from Backend-selected. Even fired the automation to set the theme, no change.
Issue resolved by upgrading to 114.0
That works too, but #6603 resolves it.
Thank you for the quick response.
