Regressions in "Load Other Example"

[ssokolow]

As of 2023-05-30 at 1:42 AM EDT, whatever version of Svgbob is used on https://svgbob-editor.netlify.app/ is mis-rendering various pieces of the "Load Other Example" document.

I didn't want to screenshot every little mistake, but here are some of the more noticeable ones:
