dojox.fx.highlight tests fail on Safari

[guest]

Instead of fading to the background colour of the object, everything fades to black, then snaps to the correct colour.

This is Safari Version 3.1 (4525.13) on OS X 10.4.11 with Dojo 1.1.0

The test is dojox/fx/tests/test_highlight.html

After fading from yellow to black (as seen here), the bgcolor snaps back to the correct colour.

So I've determined what this is, but want to blame dojo.Color somehow -- though can't figure out where why. Both safari and FF3 report the endColor as being rgba(0,0,0,0), IE7 calls it "transparent", both cases are being checked for already, so the color animation used in safari isn't reading the 0 opacity, and animating to black ( rga(0,0,0) ) ... The internal onEnd handler is setting it back properly, which is why it "works", but yes, is horribly wrong to be going towards black here.

bumping to see if anything else can be determined in core Color class, or perhaps it's even in animateProperty.

(In [14098]) refs #6399 - try setting the background style back to the orig value, which works, and shows this issue is in Color or animateProperty. needs further debugging.
