False "css-modules/no-undef-class" with keyframes

[wi4er]

I have keyframe in my scss file like:

@keyframes blink1 {
  from {
    fill-opacity: 0.1;
  }

  50%{
    fill-opacity: 1;
  }

  100% {
    fill-opacity: 0.1;
  }
}

and It throws
60:23 error Class 'blink1' not found css-modules/no-undef-class
exception in jsx template.

I think that there are actually no blink1 class :)
