[4.x]: {% css %} and {% js %} tags not working on 403.twig

[FrDH]

What happened?

Description

We wanted to style our 403.twig page, much like you'd do for a 404 page, but somehow none of the .js and .css files included with the {% js %} and {% css %} tags are being loaded. They just don't appear in the rendered HTML.

Steps to reproduce

1. Create a basic html file and name it 403.twig, nothing fancy just a basic html page.
2. Try to include one of the css files using a {% css %} tag
3. Visit domain.com/403

Expected behavior

I'd expect the page to have some styling due to the loaded css file.

Actual behavior

No css file is loaded, the rendered HTML does not include the <link> tag.

Okay, a few deployments later, everything appears to be working as expected...
Don't know why though, but for now I'll close this issue.
