Options.getJSON is not executed in a .css file that contains the same styles as another .css file

My project has the following structure:

• components/
  index.css
  • header/
    index.css
    • B2B/
      index.css
      • shared/
        • menu/
          index.css
          • subcomponents/
            subMenuList.module.css
            menuList.module.css
    • B2B/
      index.css
      • shared/
        • menu/
          index.css
          • subcomponents/
            subMenuList.module.css
            menuList.module.css

For specific project reasons, the subMenu List.module.css file (B2B and B2C) contains styles that are identical to each other. The menuList.module.css file contains a slight variation: color: var(--primary-color) and color: var(--secondary-color).

In the build, getJSON passes through the components/header/B2C/shared/menu/subcomponents/subMenuList.module.css file, but not through components/header/B2B/shared/menu/subcomponents/subMenuList.module.css. This same behavior does not happen with components/header/[B2C|B2B]/shared/menu/subcomponents/menuList.module.css, the behavior I expect from all files. Is this a desired behavior for the build process or is it a bug?

Reproduce the report with the duplicated B2B and B2C CSS paths, especially subMenuList.module.css and menuList.module.css. Trace when Options.getJSON is invoked for each file and compare the build behavior. Done means the intended handling of identical CSS modules is established and covered by a regression check or clearly documented as expected behavior.
