For inline SVG elements in HTML5, the DOM properties clientWidth and clientHeight are always zero. This breaks some librarys and makes getting the size of an svg element difficult.
As per the CSSOM View Module, the client* properties are extension to the Element interface [1], so they should be also supported for SVG elements (in contrast to the offset* properties, which are extensions to the HTMLElement interface, also see discussion for bug 649285). Every other major browser I have tested supports the client* properties (IE9, IE10, Chrome (26), Opera (12.14), Safari (6.0.4)).

It would be great if Firefox would also support them.

Yes, exactly (sorry about the confusion, when I wrote "svg element", I meant the <svg> element).
I am observing another client size weirdness (tested on - drag and rotate that green wheel, the client size is displayed on mouse release):
1. The client size of standalone SVGs returns dimensions of the page (not SVG) content.
2. When the same SVG file is viewed from a local drive, the client size is 0 x 0px.
ad 1) same in Chrome. IE returns the exact SVG size which is IMHO the only sensible approach.
ad 2) both Chrome and IE return the same dimension as when viewed from the web.
Finally I am about to release my new SVG based web app and this incorrect returning of client coords is quite serious issue for me. With deep sorrow I have to mark FF as unsupported browser :-(
Are client coords considered as non-standard ones and hence handled with lower priority?
This also applies to SVG embedded via EMBED, OBJECT and IFRAME.

All dimensions, clientWidth/Height and scrollWidth/Height are always 0.

The previous suggested workaround of using getBoundingClientRect does not work as it behaves differently when css transforms are applied. In fact I need to use both the client* properties and getBoundingClientRect to calculate which transforms are in effect.

Outer svg is a replaced box with CSS layout, and CSSOM should reflect that accordingly. r=dholbert,violet
