Prettier messing up .less files

Prettier messes up escape slashs in less files:

VSCode last version. Prettier last version.

Source:

.figcaption {
    .margin-top-1\/2;
    .large\:none;
}

Format:

.figcaption {
    .margin-top-1\ / 2;
    .large\: none;
}

This is a valid less mixin:

.margin-bottom-1\/3() {
    margin-bottom: 0.8rem;
}

This is a valid less class declaration:

label {
    .margin-bottom-1\/3;
}

That will produce the following css:

label {
  margin-bottom: 0.8rem;
}

Prettier also messes up mixins like .large\:none().

@evilebottnawi I’m guessing that it’s used to include all the styles for the classes margin-top-1/2 and large:none in the figcaption class.
