Basically unless your theme supports styling for SVG's, the editor and final output might not be great. This is here just in-case we get issues like 1px x 1px SVG's or SVG's with height and width not constrained. It's not the job of this plugin to fix your theme, just enable the use of SVG's on the platform. More work is needed, and we'll happily accept PR's for docs on how you did this for theme-X
