81770 - Dot or comma after element cancel the style description

Status: VERIFIED INVALID

(Core :: CSS Parsing and Computation, defect)

Description

[Slavic]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Win98; en-US; rv:0.9) Gecko/20010505
BuildID:    20010505

When in the CSS description the dot or comma is left after the element name,
Mozilla cannot recognise this style and ignores it. Example:
td, p {color: green; font-size: 150%;} - style is accepted
td, p, {color: green; font-size: 150%;} - style is ignored

Reproducible: Always
Steps to Reproduce:
<style type="text/css">
p, {color: green; font-size: 150%;}
</style>

Actual Results:  The style is ignored for all elements, which it sould describe.

Expected Results:  The style should be recognised and be used for element(s).

The left dot and comma are one of authors' mistake in CSS development, when the
list of elements with same style was reduced or some previously existed class
selectors for the element were cancelled. However, we can suppose that elements
with dot or comma behind simply have the empty classes: 
p. {...  =  p.' ' {... 
or empty elements: 
p, {...  =  p, ' ' {...
So the style description for these classes should be equal to the style for
"normal" elements without dot or comma.

INVALID. CSS has very specific rules for parsing, and as far as this goes we
follow the CSS rules to the letter.

verified.  We're _supposed_ to ignore any rule with a syntax error in the 
selector
