The SVGs generated by macro_railroad should display correctly on most modern browsers. Although we do not use too much CSS-trickery, we want to ensure that the most used browsers always render the same output. This is especially important if macro_railroad should ever get on a path to be included in some form into rustdoc.
Come up with a scheme to automatically test that SVGs generated for specified test-cases result in the same rendering across browsers.
A rough sketch could be a test-suite that takes certain macros as input, produces variants of the diagrams, sends them to selenium to produce a screenshot and ensure that all screenshots look the same (for some definition).
Rust's RFC1985 has a list of browsers that rustdoc should always support. As of now this is
