It looks like comment stripping might be a little overly aggressive. I'd expect it to ignore /* and */ in strings and simply return the original string, but instead it does the following:
Example 1
Input
.test-1 {
content: "/* this is just a string */";
}
Output
Example 2
Input
.test-2[name="/*"] {
background: yellow;
}
.test-3[name="*/"] {
display: flex;
}
Output
.test-2[name=""] {
display: flex;
}
