Bug 48704 – Percentage z offset in transform-origin should make the property invalid

• Component: CSS
• Status: RESOLVED FIXED

[Simon Fraser (smfr)]

transform-origin: 20% 10% 30%; should be ignored, since the % value for z offset is invalid.

It might be good to also test a lack of units on the z value:
"-webkit-transform-origin: 10px 10px 10"
This should not parse.

I added it locally and unfortunately it does parse. It is due to the m_strict usage in
parseTransformOriginShorthand, should I force it to true? Or is that something for
another patch/bug?
Cheers,

I noticed that unfortunately my previous patch caused regressions, sorry about that! This one causes no regressions but ofcourse needs to rechecked. Cheers, Rob

Hm, maybe that is expected to work. Let's leave that for another patch (if indeed it needs fixing).
