Why doesn't global import work in stylus?

Question

css

Doesn't import files @import './components/*;. Why?
I collect webpack'om.
UPD:
It seems to work, the styles are loaded, but if you open a specific file with a style imported in this way through the developer panel in chrome, it will be empty. Although the styles have been applied, nothing happens after the file is updated (changed). As if it loads once and that's it. Source-map is configured.
