Hi
I try handel to a known IE11 bug.
Usually, IE11 will just show an SVG document at the ‘default’ size,
which is 150px high and up to 300px wide.
The SVG image should not be distorted, however, unless it has some animation
– which IE11 also can’t handle.
The simplest fix that I’ve come up with until now, is to detect IE11 and
have a JS assign a body class, like ‘ie11’.
So this is a test to create a solution for an other site. :)
I will try it out and get back to you.

Thanks
Claus
