Empty suffix leads to trailing comma

[pkra]

It seems enough for

lens/converter/lens_converter.js

Line 102 in 2d0313b

if (suffix) return [names.join(" "), suffix.textContent].join(", ");

to check if the suffix is non-empty.

This seems enough

if (suffix && !(suffix.textContent.trim() === "")) return [names.join(" "), suffix.textContent].join(", ");
