mangle-selector-unparsable

A CSS selector the class mangler could not parse, left unmangled.

• It is printed to the console. A production browser bundle leaves it out.

Message

A name in angle brackets is a value the message fills in.

[csszyx] mangle-selector-unparsable: The class mangler could not parse the selector `<selector>`, so this rule keeps the original class names, which the mangled markup no longer carries.
  help: add the classes of this selector to `production.manglePreserve`, which keeps them unmangled in the markup and the CSS; if your CSS wrote the selector, fix its syntax.
  note: the parser reported: <error>.
