Help saving KaTeX equation as an SVG

I have a notebook with KaTeX cells I would like to download as an SVG, but PNG is the only option. When I copy the code into other online LaTeX to SVG editors, the spacing for multiple lines is messed up. Is there a way I can download the cell as an SVG rather than install the KaTeX fonts, printing the page as a PDF, opening in illustrator and then saving as an SVG?

Some of links at html - Is it possible to take a screenshot of a web page as an SVG image? - Super User seem interesting (I haven’t tested them).
