The names of the reference contain spaces #5102
Description
Description of problem
URL to affected spec or repo:
https://w3c.github.io/ruby-tts-req/
What happened (e.g., it crashed)?:
When the name of a reference contains spaces (like 1 and 2), the generated HTML id attribute value will also contain spaces, which violates HTML syntax.
Expected behavior (e.g., it shouldn't crash):
Either explicitly prohibit spaces in the names of references, or replace spaces with hyphens/underscores in the generated IDs.
