That file that Sass is complaining about hasn't changed in a few years.
Have you recently upgraded to vue-cli v4?

It's new project, I haven't tried this code on vue-cli v3.
This is version of sass-related packages:

node-sass: 4.13.0
sass-loader: 8.0.0

The error is dissapear if to change inline comments style. This code is working:

abbr[title]
  border-bottom: none // 1
  text-decoration: underline // 2
  text-decoration: underline dotted // 2

Error occures only with dart-sass. Compilation with node-sass works properly.
