Scalable Vector Graphics (SVG) Plug-in and the Featured Image

I realize this may not be a theme specific problem, but I want to ensure I explore all angles.

I’m attempting to use .svg files as featured images. I know the plug-in basically works, at least within the body of posts as I’m not experiencing any problems there, but when I use an .svg file as a featured image for the post, a generous amount of extra white space is added above and below the image.

Screenshots of SVG versus PNG:

I’m wondering if this has anything to do with the problem?

Regardless, I’m ultimately wondering how to address this. Is there an edit I can make to the .php files to force a static size?

Thanks in advance.
