602207 - <animateMotion><mpath> uses path's "transform" attribute on <path> elements, which it shouldn't

Status: RESOLVED FIXED

(Core :: SVG, defect)

Description

[Daniel Holbert [:dholbert]]

STEPS TO REPRODUCE:
 1. Load attached testcase.

EXPECTED RESULTS:
 Gray square should be inside of the green-outline rect.

ACTUAL RESULTS:
 Gray square is inside of the red-outline rect. (indicating that <animateMotion> is using its <path>'s transform attribute)

Opera/Webkit give EXPECTED RESULTS, mozilla-central trunk gives ACTUAL RESULTS.

In this reference case, I've moved the <path>'s transform attribute to its parent <g> element.  So, the path's rendering (the purple horizontal line) is unchanged. However, that's enough to get us to do the right thing w.r.t. <animateMotion> elements that target the path.

Requesting blocking2.0, as this is something broken (and non-compatible with Opera/Webkit) in a new Gecko 2.0 feature.

Also shouldn't be too difficult to fix.
