Bug 84216 – REGRESSION(r112177): Numbered list item rendered bulleted

• Component: CSS
• Status: RESOLVED FIXED

[David Barr]

What steps will reproduce the problem?
1. Create a <OL style="list-style-type: decimal;">
2. Append <LI> children with "list-style-position: outside;"

What is the expected result?
A numbered list item

What happens instead?
A bulleted list item

Confirmed with WebKit nightly, Version 5.1.5 (6534.55.3, r114368).

Consistent with my first guess, manually narrowed to:
http://trac.webkit.org/changeset/112177

"cssText should use shorthand notations"
https://bugs.webkit.org/show_bug.cgi?id=81737

"cssText should not generate literal 'initial' in shorthand properties"
https://bugs.webkit.org/show_bug.cgi?id=82364

Patching WebCore::StylePropertySet::getShorthandValue to return inherit or initial respectively:
list-style: inherit outside inherit;

Whereas, without that change the inspector displayed:
list-style: outside;
list-style-type: initial;
list-style-image: initial;

Could be a shorthand parsing issue.

Apparently my change exposed an existing bug in parser :(

[David Barr]

I've thought about it a bit more after discussing on IRC.
The cause appears to be that StylePropertySet::getShorthandValue()
is not bailing out when there are not enough longhand rules defined
to form a corresponding shortHand rule.

There is at least one shorthand that does not imply ommitted values, -webkit-transform-origin.
