tex2svg-page: global svg cache not rendering in safari #44
Description
When running tex2svg-page on a set of HTML files, (both litedom and jsdom), math is rendered correctly when cache is none or local, but when the cache is global, latest safari on macos and on iPad (as well as chrome on iPad, which I think uses the safari webview) fail to render the SVG, leaving blank spaces.
Both chrome and firefox render correctly with the global cache, it is only safari which seems to have issues.
When using the mathjax javascript with global cache on the site, instead of pre-rendering math, everything is rendered correctly, so there seems to be some difference between pre-rendered by tex2svg-page and rendered live on Safari.
