When using the migrator for modules, if there is any rule in the file preceding an @import directive for a partial which uses sass variables declared in that file, the tool fails. The following error message is produced:

Error: This stylesheet was loaded by a nested import in minimal.sass. The module system only supports loading nested CSS using the load-css() mixin, which doesn't allow access to variables from the outer stylesheet.

The error is not documented, and I couldn't find it anywhere in this repo outside of a test spec which didn't offer much more insight into the cause. In this failure case, it's a little confusing as output, because there are no nested imports.

Expected behaviour: The migrator does not treat non-nested imports as nested.

Minimal reproducable example:

minimal.sass:

$text-color: #fff

body
    background: #000

// Import partials.
@import "minimal/base"

_base.sass:

body
  color: $text-color

command:

$ sass-migrator module -dv ./minimal.sass
