css-modules-transform + postcss + generateScopedName does not work as expecting

[a-x-]

input:
a.css:

.foo { color: red; font-weight: bold; }
.bar { color: red; font-weight: normal; }

output:
a.css:

.lib-a-a-foo-XcD0 {font-weight: bold;}
.lib-a-a-bar-wEd3 {color: red; font-weight: normal;}
.foo,.bar {color: red;} /* <<< generateScopedName omited in postcss optimized selector */

@a-x- have you resolved the issue using processorOpts?

I canceled trying

I created new babel plugin babel-plugin-transform-import-css for bundling css-modues to js eventually
