183038 - CSSOM creation of @import rules messes up sheet ordering

Status: NEW

(Core :: CSS Parsing and Computation, defect, P4)

Description

[Boris Zbarsky [:bzbarsky]]

This is spun off bug 107567.  I'll try to attach testcases later tonight.

The right approach may be to make the @import rule kick off the child sheet load
upon being inserted into the parent sheet like we do for <link> and <style>.

Please do _NOT_ set the priority on my bugs.  I can do it myself, thank you.

Another option, now that bug 98765 is fixed, is to push all the order-checking
and such down into the parser, eliminate this business of passing back an
nsISupportsArray, and change the appending function in this case to insert the
rule into the sheet in the right place.

This is still an issue.  See the comment right above mozilla::css::Loader::InsertChildSheet which explains the problem pretty clearly.
