bug#37159: 26.1; svg images in eww

[Tomasz Piotrowski <tpiotrowski@fizyka.umk.pl>]

Well, my opinion on this is that either I have to keep switching to Chrome to use wikipedia, or I could use eww for my work. I don’t know how many others have the same issue, but it is a serious flaw in eww from my point of view. Many thanks to Lars for pinpointing the reason of certain svg images not rendering properly in eww.
