1330503 - stylo: URL values in CSSStyleSheet.insertRule and rule.style.setProperty are not recognized correctly

Status: RESOLVED FIXED

(Core :: CSS Parsing and Computation, defect, P1)

Description

This seems to be a common failure pattern revealled by the style system tests. I'll investigate why this happens.

So they are explicitly dropped because of lack of ParserContextExtraData [1].

Looking at the code, I guess we can probably put ParserContextExtraData to Stylesheet, so that we don't need to pass in that every time when we want to parse something.

Yeah I've seen a lot of logging around that.

Or the PerDocumentStyleData. Unless it differs between stylesheets?

They are definitely different between stylesheets. We would probably need one in PerDocumentStyleData as well, for style elements and attributes.

Oh, probably no need for style elements, because they have their own stylesheet.

Comment 5

[Xidorn Quan [:xidorn] UTC+11]

Now I successfully make it parse, but it seems inserting rule doesn't affect the computed value... probably need to investigate what happens in the restyler.

[Xidorn Quan [:xidorn] UTC+11]

Hmmm, it fixes much fewer issues than I thought... I have a WIP solution, but given it's not that helpful, I decide not to complete it at this moment.

Over to xidorn with the other url stuff.

I believe this has been fixed in some dependency of bug 1343964.

The remaining failures which marked with this bug is actually bug 1356494.
