Bug 173301 – REGRESSION(r209495): materiauxlaverdure.com fails to load

• Component: CSS
• Status: RESOLVED FIXED

[Ryosuke Niwa]

materiauxlaverdure.com fails to load on STP and Safari 10.1.x.

WebKit's getPropertyValue serializes the compute style value of '{name: \"flat\"}' as '{name: \"flat\"}'
unlike Chrome and Firefox which serializes it as "{name: \"flat\"}"

Because the website only strips away double quotation marks, this results in the website not loading in Safari.

That comes out of the mootools library, so this could affect more sites.

[Chris Dumez]

var content = element.getStyle('content');
if (content) {
    content = content.replace(/^\'/, '');
    content = content.replace(/\'$/, '');
    configs = JSON.decode(content); // This fails.
}

[Ryosuke Niwa]

This regressed in Safari 10.1.

[Ryosuke Niwa]

This is a regression from https://trac.webkit.org/changeset/209495

[Ryosuke Niwa]

Now interesting. The old serialization was wrong but in a way that was compatible with mootools library. We were serializing it as '{name: "flat"}' instead of '{name: \"flat\"}' so eval worked.

I can't find any uses for CSSSerializationQuotationMode::Single in this patch. Am I missing something obvious?

Oops, that's a good point. I iteratively removed each instance of ::Single but we don't seem to have one anymore.
