pdr,

Can you please explain the workaround that you are referring to?

As you can see in this fiddle: http://jsfiddle.net/nSUEs/1/

The problem is that the stroke is being clipped and it seems impossible to
make it show up.

dennisk, you can work around this manually by increasing the size of your
SVG element. It's painful, but it does work.

pdr,

Wow, thank you for the extremely fast response. The problem with the
workaround is that that requires calculation of the boundaries of all
elements. Our use-case is for complicated SVGs with nested groups and
unpredictable stroke sizes that are set by javascript. Are there other
workarounds that will work automatically?

Should we hope that this issue will get some Chromium love? It seems to
work as expected in the latest Firefox25 and IE11.

dennisk, you can use getBBox() or getStrokeBBox() to get bounding boxes of
things. There are some issues with those approaches though, and they are
not easy to use :/

Because 2 other browsers ship this, I think we have reached the bar for
implement this in Chrome/Blink. Personally, I have several other projects
ahead of this in my queue, but I'd be happy to review patches in this area
or give someone pointers to fixing this.

Seems like overflow:visible on outermost svg elements that are inline in
html works in Firefox, TC: http://jsfiddle.net/7Z4KP/.

http://code.google.com/p/chromium/issues/detail?id=231577

Firefox treats 'overflow: auto' as 'overflow: hidden' in svg, contrary to
what the SVG spec says, but more in line with what CSS says (even if it
doesn't make sense to display with scrollbars like CSS asks for in this
case). Opinions on this? Firefox is currently the only browser that
treats 'overflow: auto' as hidden.

Some discussion here: http://www.w3.org/2011/01/19-svg-minutes.html#item07
W3C testcase:
http://dev.w3.org/SVG/profiles/1.1F2/test/svg/painting-marker-05-f.svg

I don't think firefox is correct using hidden as auto... but hey, this
topic is about "overflow: visible", I think "overflow: auto" is out of
scope from here.

SVG does not respect overflow:visible.

For standalone svg documents, always clip to the viewport ('auto' acts
as 'hidden').

For 'overflow: hidden | scroll' on any svg element: clip.
For 'overflow: auto | visible' on any svg element: don't clip.

New behaviours for stand-alone svg documents:
* overflow-x and overflow-y for controlling each scrollbar independently is
now supported.
* overflow:scroll will display scrollbars regardless of the svg overflowing
or not (as required by CSS).
* overflow:hidden will cause overflow to be clipped away and scrollbars to
be hidden.

I believe I am still seeing a variant of this clipping behavior in Chrome
40 (with overflow:visible set in the CSS). It occurs on the ends of paths
that touch the boundaries of the viewport and have fill=none,
stroke-width=<something biggish>, so paths being used as lines essentially.
The additional stroke appears to be what is getting clipped. I can open a
new case if that is what needs to happen. A pic of the output with the
stroke width set to a large number is attached.
