SCSS source maps ignores deep nesting

[aTei]

Expected behavior

Source maps are generated correctly for deep nesting (import within import). So when I click on the source map link in DevTools It should open related scss file (featured-on.scss).
What I see in DevTools:

Actual behavior

It opens "base" file

System configuration

• Sprockets "~> 4.1", ">= 4.1.1"
• Ruby 3.1

Example

SCSS is bidirectional which makes me use deep nesting. So I have application-ltr.scss and application-rtl.scss. And they are doing import like this

@import 'rtl';
@import 'application/require_all';

require_all.scss looks like this

@import '0_vars';
@import '1_mixins';
@import 'sprite';
@import 'base';
@import 'aggregate-score';
...

config

  config.assets.debug = true
  config.sass.inline_source_maps = true
  config.sass.line_comments = false
