87999 - selector *:not(X):pseudo-element does not consider the negation

Status: RESOLVED FIXED

(Core :: CSS Parsing and Computation, defect)

Description

[Daniel Glazman (:glazou) (not active in Mozilla any more)]

When a chain of simple selectors contains

    1. a universal selector *
    2. negations
    3. a pseudo-element

the negations are dropped by the CSS parser.
This is because the CSS parser generates the following structures :

     pseudo-element     ->     universal selector
                                         |
                                         +--negations

and does not check if negations is null or not trying to simplify that
representation and get rid of the universal selector.

Fixing this bug is needed for Composer.

Checked in (trunk) ; drivers approval for branch since it blocks AllTags mode
rewriting in Composer.

I meant "drivers' approval requested". Sorry for spam.
