I use SVGs all the time in Edge, styled appropriately. Edge however considers (as the spec says) that the bounds of the image are at the bounds of the "page" (as Inkscape sees it, in my experience)

I do The Bad Thing™ with inline styling on occasion, but I've had no problems:

<img style="width:100%;height:auto;" alt="header" src="https://zaibatsutel.net/zaibatsu-wide.svg">

Works 100% fine in IE using a layout kit like Marx or Twitter Bootstrap every time.
