Summary: Animations on 'opacity' → Animations on 'opacity' of SVG <foreignObject> don't invalidate correctly

testcase 1

 1. Load testcase

EXPECTED RESULTS: both top half & bottom half of testcase should animate smoothly to lime over 2s, leaving a plain lime rect

Bottom half of testcase remains unchanged, until I force a window-refresh by e.g. clicking titlebar or clicking outside of window

As noted in the label in the testcase, the bottom half of the testcase is a foreignObject element.

FWIW, the actual animation targets a <g> element that is the parent of both halves of the testcase.

This also isn't SMIL-dependent, actually -- I can trigger this by modifying the opacity of the <g> element in Web Developer Console.  Non-SMIL testcase coming up next.

testcase 2 (no SMIL)

This testcase doesn't use SMIL -- it instead uses script to tweak the opacity after 500ms (as a poor-man's substitute for MozReftestInvalidate).

EXPECTED RESULTS: testcase 2 turns entirely lime after 500ms
ACTUAL RESULTS:   bottom half doesn't change until you force window to invalidate

Looks good!  r=me, with one suggestion:

>diff --git a/layout/svg/base/src/nsSVGForeignObjectFrame.h b/layout/svg/base/src/nsSVGForeignObjectFrame.h
>+  virtual void DidSetStyleContext(nsStyleContext* aOldStyleContext);

Could you add the shiny new MOZ_OVERRIDE keyword at the end of that line, before the ";"?  That way we'll notice (with a compile error, in some compilers) if the inherited function ever changes its signature without updating this code.

You need to #include "mozilla/Attributes.h" to use it.

For reference, see:

We should revert this from Aurora (Mozilla 11). Daniel, could you do that please?

backout patch for aurora

Sure.  (to be clear, this is due to the regression this caused, bug 713413.)

Requesting approval to backout from aurora.

FWIW, this appears to have regressed between Firefox 3.6 & 4.0.

Regression range was:

Tentatively blaming the biggest bug pushed that day, bug 564991, since there weren't any csets that mentioned SVG, and bug 564991 is invalidation-related.

Verified this using Firefox 12 beta 5 on Windows 7, Mac OS X 10.6 and Ubuntu 11.10.  Loaded the test cases attached (testcase1 and testcase2) and  both top half & bottom half of the testcases animate smoothly.
