If you delete all javascript from that pen, remove the circles from the svg, and add

svg .mark {
    transform: rotate(180deg);
}
you will see the same thing still happens. I don't know if it's a browser bug, an SVG thing, something specific to the way your page is styled or whatever else it could be, but it's the same whether you use GSAP or not.

 

It's not a solution, but I'm not too familiar with SVG and it's quirks yet so I don't have much advice to offer, sorry =(

Looks like Jamie is right. Even though the link is from Microsoft.. it covers zooming and panning in SVG.

 

http://msdn.microsoft.com/en-us/library/gg589508%28v=vs.85%29.aspx

 

An excerpt from that resource might explain that behavior which is not a GSAP issue, but the way SVG zoom and pan works in the browser:

 

Normally, SVG graphical objects are drawn relative to (that is, within) this user space (that is, user coordinate system). For zooming and panning with relatively static graphics, SVG graphical objects are generally never moved within their user coordinate system; instead, the user coordinate system itself is moved (along with all of its “attached” graphics) within (relative to) the SVG viewport. Thus from the viewport’s perspective, the graphical objects have moved. Stated another way, you generally move or transform the user coordinate system that graphical objects are “attached” to, not the graphical objects themselves.

 

Does it also happen if you use the browser zoom controls.. not the zoom / pan controls of SVG.

 

Also what browser dis you see this in?

 

Just my two cents, or one :)

Hey, thanks for the replies

 

sorry about the bloated code example

Not shure what you mean, the problem was with browser zoom initially.

 

Turns out Firefox has some problems with svg element transform origin as well. Found some solutions on stackoverflow, alternatively you could just wrap the animated elements into seprate svg-s and transform those, avoiding all the innter svg schinanigans.
