Selectors with a class after the pseudo-element

[bin1357]

Inconsistent behavior in the parser and strigifier when working with selectors with a class after the pseudo-element.

Expected behavior

Any output should be accepted as an input without errors

No error case

Input

.input::placeholder {
  &:not(.noAdaptiveTypography) {
    display: inline
  }
}

Output (get error case)

.input::placeholder:not(.noAdaptiveTypography) {
  display: inline;
}

Lightning CSS Playground

Error case

Input

.input::placeholder:not(.noAdaptiveTypography) {
  display: inline;
}

Output (get error case)

/* ERROR: Pseudo-elements like '::before' or '::after' can't be followed by selectors like 'Delim('.')' */

Getting the similar issue if you accidentaly target some element like br after pseudo element, e.g.:

.selector::after br {}

This isn’t valid of course, but maybe Lightning CSS can be forgiving in these cases?

Edit: just saw similar issue with suggestions on how to approach this, so ignore my comment
