1017871 - SMIL animateMotion broken if keyPoints is specified without keyTimes

Status: RESOLVED INVALID

(Core :: SVG, defect)

Description

[Jonathan Watt [:jwatt]]

It seems that SMIL animateMotion with keyPoints that have decreasing values was broken some time between 2014-02-14-mozilla-central and 2014-05-26-03-02-02-mozilla-central.

Attachment: testcase

The small red rectangle should animate around the black one.

Comment 2

I suspect this was "broken" by bug 974698, which made us stop honoring keyPoints if keyTimes is unspecified.

See spec quote in bug 974698 comment 0.

So I think this is INVALID. (Note that Chrome refuses to animate it, too.)

Attachment: testcase, with keyTimes="0; 1" added

Here's a testcase with a keyTimes attribute added.

This makes the animation play just like it did in older Firefox versions.

Resolving as INVALID per comment 2 & the fact that "keyTimes" fixes this (as I'd expect it to, per bug 974698).  Feel free to reopen if I'm missing something.

Also, clarifying the summary to drop the "decreasing value" part. (I get the exact same results [no animation] if I swap "1; 0" for "0; 1" in the original testcase.)
