I recently ran into this. I was putting an SVG into an <img> tag and sized it with CSS. In every other browser, it worked as expected. The SVG filled the space and stretched to the set dimensions. In EDGE, the SVG appeared tiny at the top-left of the space the <img> took up. I could not figure out a way around it. Had to convert it to a PNG. It seems that it handles SVGs as background images just fine.
